Yesterday the hard drive containing our Hyper-V VM files crashed. I restored the files from a backup to a new hard drive and everything seemed fine. Today all of our websites are loading extremely slowly or not at all. I've run an optimize on all MySQL tables, verified load is low and memory and hard disk usage is low. Doing a 'netstat -n | grep :80' shows only a handful of connections, mostly from my shop. I've tried restarting MySQL and Apache with no change. I'm at a loss as to why this is occurring. Can anyone offer any pointers or advice on what to check? Is there a way to test the databases?
