UPDATE: Google finally has a status page for Gmail here it is:

It’s very annoying when my Gmail goes down…

Gmail status page:

“a percentage of our users seeing ‘Server Errors’ and ‘Oops’ messages when trying to log in to their Gmail accounts. We realize that many of you depend on Gmail to communicate and assure you that all hands are on deck to fix the error. While we do not have an exact time until resolution to offer, this is currently our top priority and we’ll continue to post updates as they become available.”
