This happen often?

confirmed, they are off!

Strange..

Server mightave overloaded, but then it should've switched to backup, DDoS?

they are back! horay!

Yep, back.

Thankfully it didn't last long :)

Is deepbit offline again? Both my miners are not connecting, and when I visit deepbit I get this msg:

The page you are looking for is temporarily unavailable.
 Please try again later.

I guess so. They're out for me too.

I guess this goes to show ya -- better have accounts set up with more than one pool, so you don't waste valuable mining time.

deepbit is offline for me  :-\

set my miners to mining.bitcoin.cz till they're back again.

Bet btc guild is going to get overloaded :P

Yep offline for me too :(  Good time to change to swepool.

BTCMine, here we go!!!!!

there goes slushpool

Deepbit down,

Slush's website is reporting Bad Gateway, but mining still works.  Looks as if the website is getting hammered from people trying to switch.

Looks like its time to do some dust cleaning :P

http://kradminer.com works :D

http://kradminer.com?device=1  (http://kradminer.com?device=1)  (for the second card )

http://kradminer.com?device=2 (http://kradminer.com?device=2)  (for the third card )

http://kradminer.com?device=3 (http://kradminer.com?device=3)   (for the forth card ...)

http://kradminer.com (if you only have one..)

Slushs pool (the website) is also offline. But the mining still works. Got one accepted block since I cant reach the page any more.

well a ddos attack.. we could have expected this to happen sooner or later

Decided it was a good time to permanently switch my 1.7GH to BTCMine...  ;)  I wonder how much deepbit's overall pool will drop because of this downtime?

So far I have been happy using this pool. The only thing we need to know is who is DDOS attacking Deepbit and why?

Oh well, btcguild here we cum.

http://i.min.us/ic8WGs.png
i like!

I just took my 1.2G hashes to BTC Guild.  So far so good. :)

No fees! Yay!

Any guess on the major pools that make up OTHER?

Not pools.  Solo mining mostly I think.

no way most of other is slush and deepbit.

i wonder if deepbit being down will cause a huge difficulty decrease. if enough people don't switch there miners to different pools i could happen. 

it looks like the overall speed hasnt decreased much yet. so seems like most are staying on top of things.

slush down too?

yep.

The website is.  Miners are still getting work.

The interesting question is whether the parts that acknowledge that work and account for it are down with the website or if they are separate.

I was a few confirmations away from receiving a payout at Slush's pool.

I'm leaving the miners up until I see if that comes through or not.

EDIT: And just after posting this the website is back up.  The work of my miners was recorded during the website outage, and two blocks were found since the time of the last successful refresh.

I hope btcmine or any other pool wont be next
someone is really pissed ... or just bored.

perhaps a well equipped hacker or dos kiddie got sick of seeing bitcoin being monopolized.


It does not bother me one bit. my 1 g/hash + is happy over at btcmine.com

ya cause bidding pond is also down. maybe there were hoping to decrease the difficulty at least for a while

mine was happy at deepbit, until it got attacked, so.. ;]

I hope pool owners will take some precautions now..
btw. how can one stop a ddos attack? or defend against it?

firewalls can be optimized and improved to prevent denial of service attacks, perhaps bitcoind could be improved a bit too to decipher good from bad tcp packets on port 8332

I see deepbit as down... now mining @ http://bitclockers.com/ up and running
pool.bitclockers.com 8332

It's a clever idea to DDOS the major pools in order to decrease difficulty.  However, is that sustainable?  A DDOS would have to continue for a day or more in order to impact difficulty, I'm guessing.  Can anyone provide some math to show how difficulty would be impacted by 50% of the miners were offline for 1 hour, 12 hours, 24 hours, 48 hours, etc?

After difficulty decreases, watch to see which major new miner or pool comes online.  Perhaps they were responsible.

I always thought an easier way to manipulate difficulty would be:  Legitimately take yourself offline, let difficulty decrease, then come back online to generate more coins at lower difficulty.  When difficulty raises, take yourself offline again.  An entire mining pool could do this.  Again, math would be needed to reveal the profitability of such a move.  Mining time lost while offline during high difficulty could be made up by increased profits while online during low difficulty?

That should not be a problem. Often, botnets are used to facilitate DDoS attacks. Since the infected computers are most likely spread all around the world, there will always be enough of them online to continue the attack.



Well, that would be too obvious. I don't think anyone would be this stupid, but I have underestimated people's stupidity before...



But why would you take yourself offline? Even if the increased profits during low-difficulty phases would make up for the profits lost while being offline, it would be more profitable to take out another pool. If another pool goes down, you still benefit from decreased difficulty, but you do not have to stop mining.
And since you can buy access to botnets, there just has to be somebody who is convinced that the additional bitcoins he creates will be worth more than the dollars he paid for the botnet. Or maybe he even paid for the botnet in bitcoins...


Anyway, I will check on deepbit tomorrow. Had my laptop mining for them and was less than 0.011 bitcoins away from payout :(

I am happily mining @ Bitcoins.lc  ;D

If this leads to difficulty decrees, then AWESOME!

 You don't have to think that far ahead to realize that even if you get difficulty down for one retarget, it will bounce back with a vengeance when the network compensates with the retarget after that – with the lowered difficulty it would take very few days for the 2K blocks between those retargets to be generated, so there would not be much time to reap any great benefits from the attack.

Not that I would put it beyond anyone to try, but I think this is because someone has decided to prove the much-discussed point that having so much of the network's power tied to a few entities is a less than optimal for the health of bitcoin.

They were working fine earlier today... I hope they will be back up. Or if they could post some news? Anyone got any tweets or something from the official deepbit.net?

I did some posts on this situation in my thread and in IRC channels.

So whats the scoop?

Is anyone elses eyebrow a little cocked at the fact that "other" is  75% of hash distribution?(bitcoinwatch.com)  Do we think it is just solo miners or a secret pool of cia super computers trying to destroy the block chain?

What about the opposite attack?

Since people like to speculate about governments' displeasure with bitcoin, couldn't they play by the rules, add tons of hashing power to the network, get the difficulty sky-high and then just pack up their marbles and go home?

Block generation time then sky-rockets and thus the elapsed time until a difficulty reset.

Not that I think this scenario likely, but attack motivation may be more than directly economic.

Other is everything else that bitcoinwatch isn't directly getting hashrates from. Includes smaller/newer pools that haven't contacted bitcoinwatch to have their pool added yet, solo miners, and, at the moment, it's not calculating slush and deepbit because of various reasons.

There's at least 3 or 4 pools that have popped up recently that bitcoinwatch doesnt track, continuum, bitcoins.lc or whatever, and bitclockers to name a few. The site has no way of knowing about every pool in existence until those pool operators contact bitcoinwatch with a hashrate address for their pool.

Thats a good point.

All this attention on deepbit, and their nearly half stake in the total hash rate.... not too many people seem to point out that "other" is just as big, and even more scary than deepbit. At least with the hash rate for deepbit, we know *who* that is.... "other" could be 90% 1 person as far as anybody knows.

Has a cyberwar just started or something?

While the pools are off, you guys are doing solo mining, right?   You don't just have your computers wait doing nothing, do you?

Solo mine if viable, or switch to a different pool until pool of preference is back and stable.

Eh? Slush mining pool has been up and serving work continuously. But the web front end is getting hammered hard.

Grondilu! I'm ashamed of you! You don't expect others to secure the network for you, do you?  Get your pick and get down and dirty with us!  ;D

You're kidding but it's a serious question you're asking.

I buy bitcoins so I support the market and thus give you some incentive to mine.  Isn't that good enough?

Yeah, I'm just poking fun.  :) The French are poor miners anyway. Stick to grapes!

The reason I prefer pie charts over regular pies is the wonderful fact that even if I eat more than half the slices the rest of them will magically grow to make sure the pie chart dish always is full...

 ;)

Although from slush's thread, it looks like slush just went down as well. Maybe you want to hit the "Generate Coins" button, just in case!

Nope, the mining pool is mostly up, though the website is mostly down.

I see. The last two posts in his thread say mining is down as well. I just assumed they were correct.

Even before today, "other" was approximately equal in size to deepbit.

Do you know each and every entity that comprises "other"? Nope, neither do I.

So, all I was saying is that people are so focused on deepbit getting close to this magical 51% number, while "other" is a non-negligible chunk of the network. And, unlike deepbit, "other" could be largely composed of a single person or legal entity with malicious intentions, as far as anyone knows.

my miner was down. Diable kept repeating "unable to connect"....

does anyone think this outage will drive the price of btc up. Since i assume all of us have btc in our deepbit account that has not been paid yet that will decrease the amount of coins that will go to market to sell decreasing supply. at least in the short term, and it is possible that we will not get the coins for a long time if not ever.

Just pointing out that at the moment "other" looks about as large as I would expect it to be after you take deepbit and slush out of the stats. And I also know that there are several known entities that don't have their own slices, including a few smaller pools that are on the forums, the xkcd and reddit pools, and a bunch of solo miners with multi-gigahash setups.

I know there are reasons for people leaving a lot of btc in their deepbit accounts, but im sure most people have the default payout at 10 or even less.

Frankly, I think it's stupid to leave your btc there

Never again gonna give a shit about which pools I get into,  Solo FTW. !!!

I suggest you do the same to protect the network.

lol... with my amazing 85 megahash/sec I'd totally NOT find a block  ;D

Could theoretically find one on your first hash :P

I could also, theoretically, die of old age before I find one :P ;D

Think long term buddy,  the downside is that you end up losing time every time you check if you've won a block.

Speaking of long term...

Since slush is down, I switched over to BTC Guild... 0% fees.... assuming I was a jack ass and didn't want to donate to BTC Guild.... wouldn't their 0% fee statistically be identically payout to solo mining, just levelized?

You won't get transaction fees from a pool, at least not yet. But transaction fees are still so miniscule this early in bitcoins life. Also, "from a pool" might not be accurate, since I'm not sure if any of the newer pools that have popped up payout transaction fees too yet.

I'm surprised bitcoinpool.com isn't in those charts, there running at around 130 ghashes/s atm.

deepbit was back up up for a few minutes, but is back down again.

yes if your not paying a fee then pooled mining would be just like solo mining without having to wait for the full 50.

yes, it`s back down... :'(

Its back up, but payout isn't working...
Edit: I also can't change my payment address

The upside to deepbit dying is that the chain isn't so heavily dominated by one pool anymore. The more smaller pools there are the better.

I dont think it will die, just like how Slush's pool didnt die when it went down
Just get smaller.

right now deep bit is saying it has 0 gh/s. that has to be some kind of error

Might be down again while he fixes payouts.

Everything seems to be working now, but pool hash rate is down to 680GH/s.  It'll be interesting to see how much it recovers to original numbers.

It damn well ought to.  From a business perspective, anyone mining with one of the affected pools (regardless of their reasoning) had their cost of doing business go up severely (akin to breakage/spillage/etc. from a manufacturer's perspective).  Those outages, from my vantage point, have affected operations for a quarter to half of a day.  Said another way, a quarter to a half of a day's production has been lost by people using those pools.  Furthermore, difficulty is such that it is statistically unfeasible for those miners to have switched their hardware over to solo mining, as you can't make up the difference in half a day assuming an average mining setup (average in my mind is 1 or 2 GH/sec).  Even if you had (what I consider to be) an "above average" setup with 15 Ghash/sec or so, your average block generation time running solo is still a day or more.  So yes it should drive the price up.

Although your question was not should it, but will it.  The problem is miners are essentially kids.  Note that I didn't say minors, I said kids.  As in, someone with the mentality of a child.  That's the only way to explain the kind of irrational exuberance that you see with people dumping gobs of money into mining.  It looks like the kiddies will continue to sell their bitcoins at the severely undervalued price of $8.30ish.  I say severely undervalued because I believe bitcoins will go to $1000 in 2 or 3 years, and the kiddies will realize they could've been millionaires by holding on to what they minted with spare video cards and free electricity in mom's basement.  I can't help but think of the story of Easu, the guy who sold his birthright for a bowl of soup.  But I digress..

Lol @ Esau.


You can definitely tell that deepbit went offline by looking at the difficulty charts.  ;)

http://bitcoin.sipa.be/speed-lin-2k.png

Yup, keep trying to drive up the price of Bitcoins.  You'll have to sling a lot of propaganda to make them worth $1000 though.

"Cost of doing business" was minimally impacted with Deepbit and slush's pool offline.  Miners simply switched to a new, unaffected pool, even if temporarily.  Nobody in their right mind would try solo mining when they can easily join a new pool for a consistent pay out.

An easier way to drive up the value of Bitcoin is to educate new users about it and offer compelling products/services for sale, creating a market where Bitcoins can have actual value.  Or set up a money laundering operation.  That'll get your $1000 valuation, guaranteed.

/meaningless/

Note : Payout was not so consistent in the last hours for those in a pool.

Getting a lot of "Problems communicating with bitcoin RPC", even though the site seems to be up and everyone else says it's working.
I'm also seeing a much lower hashrate on the site than I should be.

Is it just me or is the site still fritzing?

Edit:
Doesn't seem to be happening with any other pools so I'll just assume it's a problem on their end.

getting it too and i think its killing my hash rate im 1/2 the avg i was be for this mess

why I always have the “Problems communicating with bitcoin RPC”  problem? ???

what‘s the bitcoin RPC used for?

is it only used for computing the average speed in last 10 minutes？

Well, RPC connection problem refers to problem communication with your pool. It loss of data occured when your miner send result of his work, there is a chance, that work is wasted. I am not sure wich miners engines failsave in that situation.

Yes and IMHO this is a good sign - it shows that non-professional miners still make up for a large part of the hashing power. It seems mining is not yet as monopolized as I had thought.

I hope it will stay that way because that's very good for the bitcoin ecosystem.

Deepbit's hashing power is now 1251 GH/s.  I think it was around 1600GH/s before the downtime.  So about 22% of people moved on to other pools?

0% proportional fee for a few days, I like!!!!!

https://i.imgur.com/OFrOn.jpg

Gee, how many pools have had this for ages now? 

Oh, I completely missed this thread. Yes, my pool was DDoSed - around 100Mbit/s of incomming traffic between 2am - 4am UTC. Then it went back to normal operation.

Btw Bitcoincharts.com is using hashrate from pools websites to draw chart. So when website is down/DDoSed and Bitcoincharts show zero % of some pool, that does not necessary mean that all pool hashpower is gone...

Ya, but their payout is not as high

Wish more people would understand that  ;)

Are you on drugs?

DDOS again.

Are you?

Mining on BTCMine (0% fee) for 24 hours = 1.17 BTC
Mining on Deepbit for 24 hours, during the 0% fee period = 1.55 BTC

So one pool had better luck than the other pool? ok

24 hours is not enough time to determine whether one pool is "better" than another. You need at least 72 hours. Maybe a week if it's a newer pool (presuming the new pool is stable).

I had almost 5 BTC for a 24 hr period from BTCMine.  With deepbit, the most I saw at the current difficulty level was 4.45 BTC.

*shrug*

YMMV.

Some pools get "lucky" on certain days.  Statistically it's just not possible for one pool to consistently "pay more", all things being equal.

I don't know about you, but personally I want to mine on the pool with the highest payout.

I have factual evidence that deepbit pays out higher, while you are just here arguing that the pool is "luckier." Alright.

I add another me 2 to the chorus.

 ERROR: Can't connect to Bitcoin: Server redirected too many  times

that's what I get for my troubles :(...


 ???

Oh also, since BTCMine has a 0% fee then why isn't EVERYONE mining on BTCMine? Because other pools have a higher payout (deepbit, in this case).

There is a little problem with DiabloMiner - it triggers the DDoS protection.
This will be fixed when i'll switch to another one. Other miners are working.

0% fees = 100% payout.   ::)

Deepbit pays out more than 100%, but less than 103% (101% to 102.7%), so it's still not as good as a 0%, straight-forward pool, statistically.

You don't understand variance. That's OK, some do.

I don't think you understand how the Bitcoin system works. In some 24 hour periods on BTCmine I will make double what I would have made on Deepbit. This is simply due to variance.

EDIT - rezin777 beat me to it

Offline again!

1:55 PM CDT

This time even the website's toast.

Good thing I have a backup pool -- and that I work from home so I noticed it after I got 0 hashes/s for 15 minutes!
15 minutes is bad, but a few hours would be worse!

GAH!!! :)
 I am down here as well, and I cant access my rig since I forgot to set the IP as static, and of course it grabs another one while I am here at work so the SSH I had setup in my firewall is no worky.   So I will be SOL until I get home to switch it over to my backup pool.

http://www.dyndns.com/

You're welcome 8)

As of 12:08 PM (actually the last 12 minutes):

pit.deepbit.net (72.8.190.23) not pingable from two different networks
website also appears to be down.

pit.deepbit.net back up.
I am going to switch to another pool for a while, while deepbit gets its network back on line.

Well, I personally use www.no-ip.com since dyndns.com left a bad taste several years back.   But dynamic DNS wont fix my problem.  Since this new ubuntu install is DHCP, everytime i reboot it, my freaking router assigns it a different IP.  I forgot to change it to static.  I have port forwarding setup on my router to forward a certain port to that specific IP for SSH.   If DHCP hands the machine a different IP, my port forwarding rules no worky.  lack of sleep and to many beers this weekend left my mind in a fog, and I didnt think to set ubuntus IP static. LOL.

Now Slush's website is down.

It was down for a moment because of migration to better server. Now it should be stable and much faster.

^ Trying to steal forum accounts. Do not login at that address.

What address?  Who are you talking about?

Looks like you're the one trying to steal people's info, not slush...

That was the link I originally was referencing.

seems like deepbit is offline again... 

Im still up here. Just checked all the workers on my rig and I am hashing as we speak.

No, it's not. You can check the pie chart here: http://bitcoinwatch.com

If you experience any connection problems, please tell me your IP address and try to traceroute to deepbit.net so we can see where it's blocked.

I may have to rescind my statement. Something is going on.  My rig is still running and computing hashes without any problems.  I even restarted the miners just to be sure, but all of my stats on deepbit.net account page is showing them as dead and not receiving any shares.  
Looks like I am switching over to BTCGuild full time after this.

Hey Tycho,
Do you want to check mine out? for some reason my account page is showing my miners as inactive, even though they are getting work and hashing.

Hmmm, it's down for me too right now.  The pool rate says "0" right now.

I realized about 10 minutes ago this was happening to me as well. I was hashing away but the site wasn't showing any shares being generated by me and even ended up showing my worker being inactive. I switched pools. Now it looks like deepbit's pool hashing power is at 0, down again I guess?

I just checked and although they seem to still be mining I have the following for my 400Mh/s, probably not right

Brian

Pool rate: 0 Gh/s

I see this problem now, working on it.

Tycho to the rescue.

cool - seems to be working for me now.   :)

Is there someone who still can't reach the website ?

i can reach it, but my stats missing some shares, while stats page was showing 0% for me, i clearly sow guiminer reported accepted shares, i keep reloading profile stats page, but those shares are lost somewhere.  every other time i've tried reloading page after seeing shares added in guiminer it always showed increased number on the site in the past.

I sent a payment of 1.67 BTC to my wallet and only received partial credit for it.
When I go into my payment history, it shows that it was processed, but when I click on the date to see the blockexplorer data, it comes back as invalid. 
Tycho, should I send this transaction data to you?

What is a "partial credit" ?
If the data in payments table is correct then you should receive this payment (may take some time to be confirmed).

Blockexplorer can show it only after the transaction is included in some block.

I requested the payout a while ago, but I will check again in the morning.

I see 3 payouts of 1.67 BTC in last days and they all are already delivered.
Are you sure that all the blockchain is downloaded by your client ?

wow this is weird are ISP's starting to block deepbit?? I can check my stuff on my phone 3G but none of my computers will connect to the web site nor the server.

I don't think anyone's blocking deepbit.  Rather, deepbit is blocking people, probably part of some DoS protection scheme.  One of my miners is blocked as well.

I'm not quite sure why none of Bitcoin's "critical infrastructure" employs a vast network of proxies, rather than "DoS protection" which is usually problematic.

All working fine for my worker, and transactions :) I was gonna create a worker for each miner (8), but I think I'll leave it, as it is working nicely.

So, Deepbit is now safe guarded against DDoS attacks ?

Someone on another thread mentioned taking down a certain pool via DDoS means, obviously this one, which would kind of annoy me, seeing as most of my miners use this pool. I've also got some on BTC Guild. If one pool is down then at least some of my miners are working :)

FWIW I am experiencing the same issue.  I don't think it has anything to do with ISP blocking and more to do with some form of DDoS protection.

 Problems communicating with bitcoin RPC
I'm getting that on some of my miners - not all just the ones that I want to work  :(

I have 2 of my miners (on two different Internet IPs) still blocked.  Such a shame too, I like deepbit better than any of the other pools I've looked at.

Please, check my thread instead of this one.
I'm not updating all the threads, sorry.

I have a script I use on all my major websites to prevent a DDoS attack. Basically it forwards flooding connections to fbi.gov the issue usually...well resolves itself.

I'm getting:

Windows cannot find '--host=pit.deepbit.net". Make sure you typed the name correctly, and then try again.

What am I doing wrong? Or is Deepbit stuffed?

I gave you a complete answer in my thread. Why don't you want to read it ?
