"Snoopy": I don't think it should be called "so much" because, as my stats page says, the site was down for 3-4 hours, which is not a tragedy, compared to a recent Skype's 4 days continuous downtime, regarding the fact that BrainKing is maintained by two persons, while Skype is owned by eBay, a really big company. Well, to answer your question, the new BrainKing rack contains 4 machines (+ a switch) and it's not an easy job to configure and finetune such a pool of servers, especially when BrainKing is not the only service which runs there. It is necessary to survive a couple of downtimes, which will finally produce a better, safer and more robust system.
