I like the switching accounts thing I didn't notice that. I do have a few accounts (one personal and others business) so it makes it easy to manage all of them if I don't have to keep remembering all their login details one by one.
Yeah, apparently it's an employee's accident. Whatever! They know when they're working on test servers or the real deal as they'd be completely different sizes and it would take hours longer to roll out on the real deal than compared to a test server not being used for anything else. I'm sure they'd have different people rolling it out live compared to testing it too.
