Mine is down also. This is actually slightly terrifying. What's standard operating procedure for recovering from a lost gmail account? And I don't mean getting the account back--I mean, your account is lost forever.
Your whole account or just the email part? If you have a real email client, you could rescue your email from it even if your account is toast. If just the webmail part goes down permanently, you can download your mailbox from https://www.google.com/settings/takeout
I still have my Gmail account hooked into Thunderbird. I don't actually use it to check my mail, but it keeps pulling it all down, so if Google's servers all catch fire, I lose nothing.
