My Gmail account suddenly started working again 2 hours ago (I did not get a reply from Google to the email in which I had to give them all the details about what happened). I feel relieved!
I missed 38 emails over the past 24 hours, luckily most people are on vacation, otherwise it would have been a much bigger problem. I am not sure if I should start downloading my mails again right now. I am a bit afraid it will close down automatically again, I’ll probably wait a few days first.
