Hi Scott, well, it happens eventually. All things fail. It's just very bad timing because someone is heavily promoting one of my sites at the moment. I usually wouldn't stress too much, but it's just very inopportune. Murphy's law, I guess.
The funny thing is, I moved to the current server because the IP address of the previous server was blocked in China. My new server was preforming great. Low loads, no blocks, etc.
I've never liked, nor fully understood, the credit for downtime policy. It ought to just be automatic. I'll look into it though. Cheers.
