Microsoft Azure Goes Dark For 22 Hours

Forget concerns about PCI and DR in the Clouds - Microsoft Azure just recovered from being offline for 22 hours.

The Azure Cloud is currently in Technology Preview mode which means unscheduled developer holidays are pre-baked in.

I haven’t written about Azure before (tut tut), however I have been following along.

In case you somehow missed the announcement from Ray Ozzie, this is the Azure Stack.

And this is what it looked like to the Azure development community for the past 22 hours:

As seems to be the case for Cloud outages, updates are posted to a support forum.  Here is all anyone knows thus far (via Oakleaf Systems):

This was obviously a significant outage and it will be interesting to understand the root cause.  These massively distributed systems are truly an enormous engineering challenge - we’ll wait to see what Microsoft (and others) can learn from this particular incident.

I look forward to exploring the security aspects of Azure with you in the upcoming weeks.
