It’s been covered in the press but we wanted to mention that we picked up the Facebook outage yesterday. Starting at 12:00UTC on 10/21 and lasting until 14:30UTC Sharing was pretty much impossible to Facebook, with the service throwing a variety of 400 and 500 errors. We had a successful test at 14:00 but it was followed by more failures.
More interestingly, oAuth, Search and Profile fetch remained completely unaffected.
