I hadn’t logged in to my Hotmail account in a while. Here’s what I got:

Now, look closely, at the bullet points describing why my account has been deactivated. Apparently I either last signed in tomorrow (-1 days ago), or I deleted my account tomorrow (-1 days ago). Guess what happens when I click “Activate Account.” It redirects me about twelve times, and eventually redirects me back to this page.

I can only assume this is the product of time travel experiments at Microsoft Research. Good job guys!
