...I didn't get any email outage at all through my Google Apps account. Call me old-fashined but when you sign up for something like that you deserve to be included if everyone else gets a complete service failure.
I can only assume this is because, remiss of me though it is, I never rely on only one route for my email to reach me, so when the web interface fell over (so I read) I was happily downloading through Apple Mail, for which the interface wasn't broken at all.
On another occasion, when the downloadable mail failed, I found the Web was fine so I used that for a few hours.
Crazy I know, but even after all these years I don't trust computers enough not to have a Plan B. How did everyone else get on..?
