poolstats seems to be a never ending story Wink Cry
My widget tells me the pool is 53TH/s, not the 25 the title of this thread indicates.
yeah, I should go away more often, pool hashrate and % of network pretty much doubled over the 10days i was away Tongue
thought I would have had access to better net but had to rely on mobile data
I'll update topic and try catch up on stuff I wasn't able to attend to while away

I just checked email, got one yesterday saying my ozcoin wallet address had changed (?!?!?).  Just went into ozcoin website and it shows withdrawal made of all my remaining coins to this other (Unknown) address.  I haven't logged into the ozcoin website in months.  Not sure who/how my address could have been changed and then all coins withdrawn in a 24hr timespan.

I use a > 15 digit alphanumeric pwd that is not repeated at any other site, and I don't have any other indications I might have been compromised.  Am I missing something obvious?  I haven't been on the forums or paying alot of attention lately, so this is possible, but I'm still somewhat troubled.  Given the current exchange rate of Bitcoin this represents a nontrivial amount of currency.

Thanks

some info on your account would be nice.

I sent that in a PM to Graet 6..ish days ago.  Understood he's been away/busy. I'll PM you as well if you like if I can verify you are a legitimate support person for the site. Unfortunately there isn't much listed on the site for support except this forum.

It is good for you to report here, but it is probable that nothing is wrong with the site - your credentials for the pool website were likely obtained by a cracker, by your computer, email accounts, or network connection being Pwned. With Bitcoin, you are responsible for your own security; there is no bank to call that can give you your money back when you got scammed. There is also no way to prove it wasn't you that withdrew the money.

You can report the theft to Police who will be glad to chuckle; with someone willing enough to file a police report because a theft actually happened, a site admin may be able to turn over what forensic evidence there is, likely just a Tor exit node IP address or an IP address of one of over 9000 rooted machines under a hacker's control (if there even is any logging - many users might prefer no logging of their pool connections if given the choice...)

I take this as well meaning (but somewhat condescending) advice.  In my mind, there are at least 2 plausible scenario's:
1) My personal security has been, as you put it, Pwned.  In this case I would be missing several orders of magnitude more coins, from other sites, in addition to at least some token amounts of fiat currency.  To date, this has not happened.  Just this one site, and just the coins available at this one site, where there is a single, non-repeated pwd on my account.  If just this site's password was compromised, I would think the site operators would have interest in this, as I've stated it's a nontrivial password hack.
2) During one of the several documented breaches of infrastructure/security, someone harvested passwords.  When the withdrawal limit was lowered, they went back and cashed out all they could. 

A response from the site operator(s) would be helpful in determining which of the above 2 are more likely.

Of course there are probably several other scenarios that may be in play here, but that is why I asked the question, rather than pointing fingers and getting fired up.

Last 3 days luck <30%
 Huh

Cool, not as bad as I thought.

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?

Bad luck or attack scammers who hide blocks from the pool.
The first 6 positions do not bring the blocks.

Is this technically possible? I thought you get work (range) from the pool, isn't it impossible for someone to claim the block as his own if he doesn't know [edit]can't change[/edit] the hash from Merkle tree?

this is incorrect, though technically possible- it is called block witholding and no-one gets the BTC, works best against PPS pools, doing it on DGM or POT will also harm the miners earnings
current #2 has over 20 blocks for pool, current # 1 joined recently, we do keep an eye on blockfinding

testing new www/db server over next day if all goes well we will move over before weekend is out.
dual xeon, 24gb ram, ssd in raid 10 - nice and quick, based in US so latency lag on stats should be a thing of the past Smiley

Wayno has been unwell, I spoke to him this evening, he will be in touch soon


In other news we plan to cut over to new server later tonight (my time) website will be down while we copy database and DNS propagates. Mined shares will be cached on mining nodes and submitted to new server after database is updated. Downtime for website will be kept to a minimum.
Migration underway

ozbot is Ozcoin's IRC bot, it announces blocks, gives stats and other useful things and can be found in quite a few Bitcoin related IRC chanels.
