I too have had problems with the web site. i kept getting, something has gone wrong.I have only now been able to get into my account and the community so i was not able to ask if it was just me. I had updated windows 10 last night and thought it was that because some of my auto sign ins had to be reset. Hope it has now been resolved.
Sounds like there was a widespread outage yesterday - on my machine the community page showed no activity for almost a whole day, something I've never seen before. I thought I'd been blocked. Let's hope it wasn't a data hack.
