It logged me out and told me that my credentials were incorrect; I thought my credentials had been stolen, so I'm kinda personally glad that it seems to be happening to a lot of other people too. I know that's a bit selfish, but :shrug:
Yes. My spidey sense went off and I told my work I'll be off for an hour while I redo all my passwords... might still do that but glad to know it's not necessarily me getting hacked.
