Since last night, Xbox Live has been having various service outages, reported on its status page. Last night, it was Netflix; today, the site reports issues with creating, managing, and recovering accounts, and with creating, maintaining, or joining matches in Call of Duty: Black Ops and Halo Reach.
We're checking with Microsoft to determine the cause of these outages, and if possible the expected duration. Did the pizza guy trip over a cord, or was it something more serious? Like, maybe some pizza also got into one of the server's vents.
