In less than 2 days of coming out with good performance numbers on object storage, Azure had an outage due to an expired SSL certificate. I remember of a very similar problem for their microsoft.com domain with expired DNS registration in the year 2000 (or 2001) during the Christmas holiday time. Looks like silly housekeeping items are causing business issues.
Microsoft's failure to renew the security certificate apparently caused
the Azure service to go down shortly before 4 p.m. EST Friday. The
breakdown prevented Azure customers from accessing files kept in
Microsoft's data centers.
