We are in the process of moving you to a new server. So the site is "running" on the new server. The problem is it takes the DNS information of what server yenko.net belongs to some time to update all around the world. So some of you may be hitting the new server and things are fast and no problems. And some of you will be hitting the old server, which is currently having some problems. It's being looked at, but that's why the site is moving off of it.
Hang in there as the DNS updates for everyone. Once everyone is hitting the new server (with 4x the processing power) you will definately notice a speed & reliability improvement.
