any plans to bring back the uswest server in the future? Edit: nevermind New "super server" US West coming up July 10th. |

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

Just started bringing all of my miners back to BTCG... I renamed a couple and added a few more since the DDoS. My miners that I had with BTCG before everything went down are able to connect, but the ones that I renamed and added are getting "problems communicating." I know in the grand scheme of things, this isn't a huge problem. It seems like the pool isn't accepting new miners? Maybe the pools aren't syncing the login names of the miners. Thought it may be on a delay similar to how the stats are, but it has been about 30 mins and they still aren't connecting. Eitherway, just wanted to make you aware. Great job on getting everything back to operational. Can't wait for the super server!

any "i'm mining at btcguild with ###" banners?
the guys at http://bleedkira.netau.net/ will give you one. see my signature for an example. I tried inserting the code from the web page but when I tell it to update my profile I get image removed. How did you get yours to work? EDIT: Never mind. Apparently I need 50 posts or it removes images  |

If you read the profile page where you can edit, it tells you need 50 posts in order to be able to have an image in your signature. |

Thanks eleuthria, you're a mighty decent person in a world of mediocre people.

Sorry for the lack of updates this morning, wake up with a migraine that knocked me back to sleep until about 5 PM.
I'm hopeful that I can get the "super server" mentioned in the header online tonight. It is a priority over the API and Historical Stats, since the pool is growing back at a fairly quick rate, and this new server could likely support somewhere between 3 and 6 TH/sec (hard to know exactly how well it will scale, especially looking at US East's speed).
I got quite a bit of sleep, so I may be up late enough to get both done, although it'll be technically July 11th.

I'm still curious why running 7 VM's on very powerful hardware is better than running one main OS, with one bitcoind and one pushpool, each of which of course would get 7x the resources. It's not like it's spreading out the risk, it's all on one piece of hardware with one network connection right?

curious if something has changed in the last 24 hours or so or if im just running a streak of bad luck. only getting about 1/10th or 1/5th of my normal shares on use east. read deepbit removed longpolling for ufasoft due to some issue and just wondering if maybe you did the same o.o oh and just got a connection terminated abnormally error as well! :S get those with a ddos normally >_> *sigh* oh well.

Pushpool and bitcoind cannot fully utilize multi-core systems. Parts of them are threaded, but certain aspects can only utilize one thread, and these are the primary sources of miner idles. Additionally, the volume of connections that connect to the servers can cause issues with the linux TCP stack, although a lot of tweaking has been done to eliminate that bottleneck. By splitting a single server into the following components: Load Balancer (pfSense) MySQL Server Pushpool Servers We exploit the inability of the programs to FULLY utilize multiple cores by giving them each a smaller load on virtual cores. This also reduces the total number of connections that each pushpool has to loop through when pushing out long polls, which is part of reason occasionally you'll see a 2-3 second miner idle when a long poll is being pushed out. The overhead of XenServer is minimal. This also means if a pushpool instance freezes (hasn't happened recently), the people connected to the server will simply be routed to a different instance of pushpool. A few seconds of downtime instead of a few hours. |

I thought it might be something like that, that's the only logical reason it would make sense, thanks for the clear explanation! I hope it goes smoothly for you/us  |

There was a brief (~10 minute) window on US East where it was tossing out idles fairly frequently. It required a quick restart (~5 seconds).
Been smooth since then [although it will now explode after I've said that].

US East is showing a similar bottleneck to the original EU (DE) stress test of about 1 TH/sec.
I've modified some of the DNS entries to try to spread some of US East's load onto the other servers. The new server may come online in the next few hours if all goes well.

I've been tweaking the DNS entries to get the split more even. US East and Central idles have stopped for the last hour or so. The new server is almost ready, but I'm making sure the other servers will sync with it when they complete a round. This server is a completely different beast from the others, so I have to be very careful before deploying it live since it is essentially 4+ servers at once. UPDATE: Two blocks finished which was enough to give confidence that the new server will properly sync together with the other servers. The new server is now online. Any DNS entry which is not explicitly used has been pointed to the new server: us., uswest., eu., nl., nl1., nl2., de2., guiminer. all use the new server. Once it has proven itself under moderate load, I will include btcguild.com generic address, and slowly make plans on migrating US Central into it. |

No its not. I'm getting "Warning: work queue is empty, miner is idle" and "Disconnected from server" followed by "Connected to server over and over again. My 4Ghash/s has dropped to 3 to 3.2 This has been happening to me for the last 14 hours now, no matter what server I choose. Just tried us.btcguild.com and get the same thing. This is of course causing me to get lower payouts and is probably not good for my GPU's either. If I run "mtr us.btcguild.com" I get zero packet loss while this is happening. Nothing wrong on my end. Also I connected all my workers to a different pool and was not experiencing this. ill give it another hour before I move elsewhere. |
