From what I saw, started as routine maintenance, and we began seeing SQL timeouts and errors on SQL East, and then all our DB servers on SQL East just vanished. Stayed gone for 5 hours at least.
I took a screenshot of the status console once it got updated with the outage info (several hours into the outage):

Pretty unhappy about the whole experience. Luckily, we have our own colo in addition to Azure.
