Bad Request
Error 400
I figured it was momentary, so went off to do other things. (So many other things to do...)
A few hours later, same thing. Next day, same thing.
This is unlike gmail. So tried a simple Google search... slow, but it did return.
Maybe Google is under a DoS attack? No news, and now Google is returning just fine, but still no gmail.
So I started searching around for anyone with a similar problem. Saw a few, though they were old.
Tried the gmail Google Group and went through what seemed to be the procedure to enter a new issue (after reviewing current open issues), but that did not give an opportunity, at the end, to open a new issue.
So, some more generic searching, using both Google and Yahoo, turned up the typical low-level support "decision tree" request to empty cache and delete cookies. Well, I'm certainly not going to delete all my cookies right away, however...
I tried a different browser and got right in - OK; we're on the right track.
I then saved my cookies (always have a backup) and looked for which cookies might be the culprit.
Got it in one: There were probably well over a hundred (!) separate cookies for the mail.google.com domain (both with and without a leading dot), that also used a path of "/mail". I deleted them, and gmail loaded right up on the next try!
Update 2009/03/20: Apparently there's a similar problem with Firefox.
