If you have pending wallet change, payouts of the account are locked (to prevent sending coins to old wallet). So you have enough time to elaborate with it.

I'm not aware of any "special security feature" of the email, it is standard plaintext mail.

I completely forgot to site localization. It's fixed now!

Pool just sent out all bitcoin payments; there were pending hundreds of payouts with total amount around 1100 BTC. As I announced few hours ago, I'll process payouts manually for some time, to be sure everything works as expected. I'm very sorry but I'm unable to process namecoin payouts right now. I didn't sleep for almost two days and I need to be more fresh while handling with money. Handling with large amount of bitcoins/namecoins is always a bit dangerous (one bad click and you had coins...) so I need to take some rest. I'll setup automatic bitcoin payouts and namecoin payouts tomorrow. Thank you for understanding.

Longer answer: "total reward" is sum of unconfirmed blocks and confirmed blocks. But *during* the block confirmation process the block is in transitive state, it's neither unconfirmed or confirmed for some time. So you'll see minor drop in "total reward" for small amount of time.

Of course, when pool is processing 30+ rounds in batch, you see such small drops more often. Especially when you're killing the webserver by F5 every few seconds .

Keep calm guys. Pool is processing tens of blocks, it takes some time.

OK, I went thru all reportings of wrong block rewards. I fixed some rounds, but currently it looks to me that they're fine and reported differences are in the range of common variance (+ some downtime during the pool recovery). So I'm going to process pending block rewards and payouts in few minutes.

Automatic payouts will be still disabled until tomorrow and I'll do manual payouts irregularly by myself, because I want to keep eyes to payout mechanism for some time. But if everything will work well, I'll enable periodic payouts every 15 minutes tomorrow.

Yes, looks like local dns caches (browser-side or ISP).

The pool currently calculates block rewards only; I'm waiting for the feedback if block rewards are calculated properly. Then I'll run block confirming process (and you'll finally see all coins as confirmed) and auto payouts.

Hi all,

after more than a day of hardcore hacking, I finally recovered the database and website to normal state. As you can see, website statistics know about all mined blocks during the website and database outage, including worker shares of loyal miners :-). Thanks to logging onto stratum nodes I've been able to recover complete shares. Some block rewards may be a bit off, because the pool was down after the attack and miners also often didn't reconnected instantly when I restarted stratum nodes, but generally I think the stats are correct.

Pool is currently calculating block rewards, but payouts are not processed. I want to give you some time for a feedback, if block rewards are calculated +/- as expected. I need some rest now, but I'll incorporate your comments then and process payouts of your mined coins.

Thank you for your support during this incident. I made significant changes to pool infrastructure from security perspective which I'll announce in detail later. Shortly said, pool doesn't hold any coins on live servers anymore. I also moved database to trusted place with limited physical access and without any consoles, Managers etc. Database is now running in undisclosed data center and on unknown IP.

We're fine-tuning mailing subsystem, there were some problems. Please be patient, emails will eventually arrive.

I'm finalizing the pool reconstruction, most likely it will be up in a hour.

Today I had a phone call with OVH guys. They told me that they have "nothing to investigate" because I'm the only who reported the problem. I asked them for logs, they have nothing more than list of IPs who accessed the Manager. These IPs are some random IPs from whole round, looks like proxies.

I'm having some troubles while setting up new database server, so all this is taking longer time than I expected. But I'm still working on it.

I do use IRC, but currently I don't have a time hanging on chat, sorry .

FYI Pool hashrate is still above 7Thash/s and it reports new blocks normally. Please be patient, I'm working hardly to get website back online.

I'm setting up server right now on safe location with physical access only, the website should be back in few hours.

No work is lost, but mining on Amazon is recommended. If you restart the miner using stratum.bitcoin.cz, you'll be switched there.

Yes, stratum.bitcoin.cz, stratum2.bitcoin.cz and stratum3.bitcoin.cz points to safe servers.

Yes, stratum.bitcoin.cz is now pointed to Amazon EC2 instances, which are safe.
