Gmail Down?

When I try to view my Gmail ^[1] account, I’m getting a “Server Error: Temporary Error (502)” message that says:

We’re sorry, but your Gmail account is currently experiencing errors. You won’t be able to log in while these errors last, but don’t worry, your account data and messages are safe. Our engineers are working to resolve this issue.

Please try logging in to your account again in a few minutes.

Very strange. Even more strange is that I can log into one of my Google Apps for Domains ^[2] accounts just fine, just not my main Gmail account.

Update at 10:30 pm: Seems to be working fine now. Not sure how long it was actually down. Around an hour or less from what I saw, but who knows how long before I checked it went down, and how soon in the interim it came back up.
