Windows Azure Restored Following Global Outage from Expired SSL Certificate

Microsoft’s Windows Azure storage was back online Saturday after an expired SSL certificate left customers unable to access their data.

The cloud service went down Friday afternoon when the SSL certificate expired and remained unavailable until Saturday morning. The worldwide outage affected HTTPS traffic accessing storage, though did not impact less secure HTTP traffic, the company confirmed on the Windows Azure Dashboard.

“We have executed repair steps to update SSL certificate on the impacted clusters and have recovered to over 99 percent availability across all sub-regions,” according to an updated alert on the dashboard Saturday. “We will continue monitoring the health of the Storage service and SSL traffic for the next 24 hrs. Customers may experience intermittent failures during this period. We apologize for any inconvenience this causes our customers.”

“That did little to console some customers. “Most of our apps are screwed up now! “WHATS NEXT? All compute instances die because someone at the data center switched them off?,” wrote one customer on a Windows Azure MSDN forum. “This is unacceptable, I'm supposed to release an enterprise app on this platform?,” added Microsoft partner MJ Fara. “Imagine how many phone calls I would have gotten by now from very angry customers. Sad.” And another partner who identified himself as Matt from Cambridge said: “Pretty amazing that the entire Windows Azure storage platform is offline globally.”

Others took it in stride, noting it was an error any customer or partner could make. “I bet a lot of people here have accidentally let an SSL cert expire, or nearly done so,” said Brian Reischl of Sepia Labs, a company consisting of former NewsGator employees, who first pointed to the SSL certificate with a screen capture Friday. “I know I have. It's easy to forget, right? It's an amateur mistake, but it happens. You end up with some egg on your face, add a calendar reminder for next year, and move on.”
