The most frustrating thing for me was the complete lack of any real communication from Microsoft. For awhile, even their status dashboard was down. I only found out about it after I got a PagerDuty alert and had to search Twitter (other people complaining about it) to confirm. We have an Azure CDN backed by a Compute Instance, and zero official notice from Microsoft about this still. I've learned more about the problem from news articles than the company that provides the service. Fortunately we haven't finished migrating the rest of the site to Azure. No emails from them, nothing. Not even a tweet on their official @WindowsAzure account. Frustrating.
