Politics, Weather, Photography, and the Dog
Wednesday 20 February 2013

Over the past two days, Microsoft Azure had two outages they're still investigating. The first, from 18:26 CST through 20:00 CST Monday (0026 to 0200 UTC Tuesday), and the second, from 13:50 to 15:27 CST (1950-2127 UTC) yesterday, affected SQL Database and related services in the Azure datacenter outside Washington, D.C.

I noticed the Monday evening outage as it happened, because when a database goes down, a number of applications start sending me emails. A couple of people had minor inconveniences, but as it happened on a holiday evening, the damage wasn't too severe.

I did not notice the Tuesday afternoon outage, which did affect a lot of people and made some of my clients very angry, because I was on an airplane. When I landed and turned on my phone, I had 300 emails from various applications and mercifully only 4 from angry clients. (Welcome home!)

Microsoft hasn't determined reported the cause yet, but given the maintenance they had planned, started, and then backed out on Sunday night, they may have a clue. They have a second round of maintenance planned for tonight at midnight CST (0600 UTC). I'll be watching carefully tomorrow morning.
