This is a normal error that happens a lot. It usually just means your server is bogged down.

Get used to 'can't connect' errors if you're on shared hosting. But they shouldn't last long. If they do, contact your host.

That doesn't make sense. I'm on a dedicated server with an Intel Quad Core Q6600 processor, 4GB DDR2-800mhz RAM, and 2x 120GB 7200rpm HDD RAID 1. :o

If you are on your own dedicated server, then check your mysql error logs and see if there is something in there about what happened at that time.

That error normally means mysql was not running - did you (or something) restart it.

That error can apear due to ddos attack. My sugegstion, check apache logs, also netstat could show you more.

This used to hapen to me when i had some nasty "friends", lol.

No. I hope it wasn't a DDoS attack. I doubt it though unless they gave up.
