It's not you, it's me.  Sometimes you might go to this website and get an error like this:
It's not your fault.  It's my server.  Sometimes it's down for hours at a time.  I asked about it, and JD said it's because both the Apache web server and the MySQL server are running on the same machine.  Apparently this isn't a good thing, and it might be fixed in the near future. #technology
