I’ve been getting a 502 error on my Gmail account for almost four hours now:

Temporary Error (502)

We’re sorry, but your Gmail account is currently experiencing errors. You won’t be able to use your account 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 accessing your account again in a few minutes.

I just got an email from them (sent to my Yahoo! account, as I specified in an error report/support request):

Hello,

Thank you for your report.

We are aware of this problem, and our engineers are working diligently to find a solution. We apologize for any inconvenience this issue may have caused.

Sincerely,

The Google Team

Anyone else having problems?

[Update 2008.08.07 11:16AM] When my alarm went off this morning I had access to my email.  I went to bed last night around 1AM and it was still unavailable.  So I was without Gmail for somewhere between 12 and 18.5 hours.
