Site downtime and errors

For the past few hours, all of my sites are plagued with 500/503 errors, and my databases keep going out and not connecting. Needless to say, my websites are not accessible, usually turn up one of many errors, and respond very slowly when they do.

I am on sabretooth (web), homie (email), and raory (mysql). I sent in support tickets hours ago. I just wanted to know if anyone else was currently having problems?
