[~1000 GH/sec] BTC Guild - 0% Fee Pool, LP, SSL, Full Precision, and More

[Duffman]

Hell no. I'd never use a pool with so high fees

I was 'donating' 2.5% for the invalid blocks anyway, this 3% fee isn't so bad 'cause the blocks get found fast.  I couldn't believe this (block found in 18s):

07.07 02:04:28   0h 00m    1    17493     0.00277254
07.07 02:04:10   0h 07m    33    580062     0.00275919

blocks getting found fast doesn't matter in the long run... it evens out.

New server is coming online later today (next 12 hours roughly).  Was having some difficulties getting out pfsense VM frontend to properly connect to the outside world last night, and I was not going to put up a brand new server configuration before getting some sleep.

good work!
just waiting for your pool to come up again

still hoping you let me mine on port 80 and delay some stats though .... but that has time until you get rid of those ddos'lers....

ARe you still processing payouts?

ARe you still processing payouts?

Payouts have been flowing steadily since about 12 hours after the attack.  I modified the code to do full precision payouts so anybody looking to leave and not come back after the event isn't going to start screaming about their 0.003 BTC that I held hostage.

Last night I added back wallet changing to the temporary account page.

Once this is all resolved and you've had some much deserved rest, it would be great if you wrote up a synopsis of the experience with an emphasis on how to stop/prevent these attacks.  It seems like information about how to perpetrate a ddos is easy to find, but information on what to do if you are the victim of one is conflicting, confusing, and vague.

Hang in there!

This DDoS is getting out of hand. Both BTC and Deepbit are down.

deepbit looks to be coming back up now.  238 Ghash and rising.

Honestly, there's only four options for fighting a DDOS:
1) Wait it out
2) Pay for bigger pipes and hope they're bigger than what the DDoSer has access to.
3) Pay for an ISP that has perimeter level filters to stop the DDoS at the frontend pipes rather than your personal server.
4) Both 2 and 3 combined.

A DDoS cannot be filtered at the server level, or by adding a firewall in front of your server, no matter what people claim.  Your ISP is only giving your server(s) access to a certain size pipe.  If you fill it, you're essentially offline.  A DDoS can flood the pipe even if you are blacklisting them, because your blacklist will not take effect until its in your pipe.

US East is coming back up again.  I'm doing as much work as I can on our new server to get it online ASAP, but I can only do so much before my day job starts becoming affected more than it already has been this last week.

The past shares on US East were lost in the transition.  The script that runs to backup the shares from RAM to the HD once per minute was timing out due to all the servers being offline.  I've modified the script to run separately for each server, so if multiple pools timeout (ie: offline), it will still complete on the servers that are available.

blocks getting found fast doesn't matter in the long run... it evens out.

I think it does 'cause you get more chances of 'getting lucky' (finding easy blocks) in the same time frame.  my daily income is up

no, you don't get more "chances"... your daily income will approach the same value in the long run. think about it: if you once "get lucky" in a small pool, your one-time-earning is much higher (you get a larger portion of the "pie")

Now we know that when BTCGuild is down, everyone goes to Deepbit. 51%

I went to slush. Im waiting for this guys to finish their present block to join them. Awesome performance regarding stales: http://forum.bitcoin.org/index.php?topic=12181.0

I joined them after reading through their thread.

They have their own pool implementation with Node.js. That's two good thing in one sentence!

[Duffman]

no, you don't get more "chances"... your daily income will approach the same value in the long run.

yes, I do get more chances.  in an hour I could be in search of x amount of blocks.  if I was in an other pool that was half as fast I would be in maybe x/2 searches.  my daily income has gone up; I get what you're saying, but the theory isn't proving itself in my case.

think about everytime you start a block, you flip a coin.  if its heads, your search time is low; and tail, its high.  10 flips every hour will probably get you more heads than 5 flips per hour.

Yeah, but the outcome for everyone in the pool is the same, more flips per hour, ultimately means more people to share with... Thats the whole point.
Of course your daily income might have gone up for now, but in the long run you earn exactly as much as you would by mining without a pool or in a 1Thash pool...

Except that there is no block, you aren't searching, and there isn't a coin toss.

Each hash you perform has a 1 in 6*10^15 chance of being successful.  The end.

+1! Thanks.

We just solved a block, servers are still going strong.  Still hoping to get our new "super server" online tonight with the internal load balancing and behind a far stronger ISP/pipe.

[eleuthria]

Current priorities with the pool:
  1) Restore full account settings functionality (email address changing, donation percent changing)
  2) Restore worker stats summary (will be using cached values, updated at 5 minute intervals)
  3) Restore API functionality


All of this will be interweaved with getting the new server online.
