Can't get into Yahoo mail/IM

The Yahoo page comes up normally, it shows me I have three unread emails, and then when I try to go into my mailbox it says:

.
Trying again doesn’t work. I checked the “is it just me” site and they say it’s just me. IM also won’t load, but there’s no particular error message, just “do you want to try again.”

I tried rebooting, that didn’t work.

Any ideas? My browser is Firefox, other frequently visited sites (and all other email accts.) loading normally.

Never mind, it seems to have gotten over its snit – four hours later.
