Microsoft’s Azure cloud infrastructure and development service experienced a serious outage on Wednesday, with the system’s service management component going down worldwide starting at 1:45 a.m. GMT.

“We are experiencing an issue with Windows Azure service management. Customers will not be able to carry out service management operations,” Microsoft said in an initial message on the outage on its Azure service dashboard.

The issue has been “mitigated and service management is restored for the majority of customers,” Microsoft said in a message posted at 1:30 p.m. GMT. “We still need to work through some issues before we can completely restore service management.”

The incident’s root cause “has been traced back to a cert issue triggered on 2/29/2012 GMT,” Microsoft said in a previous update.

At 5 a.m. GMT, Microsoft said less than 3.8 percent of hosted services suffered from the issue, and it took measures to stop the problem “from spreading across the production environment.”

In addition, Azure customers in the north and south central U.S. as well as northern Europe may be experiencing some performance problems, according to a message on the dashboard posted at 10:55 a.m. GMT.

“Incoming traffic may not go through for a subset of hosted services in this sub-region,” it stated. “Deployed applications will continue to run. There is no impact to storage accounts either.”

At 1:30 p.m. GMT, Microsoft said it was “still troubleshooting” the issues affecting these regions.

As of 9 p.m. GMT, the service management function was still experiencing a worldwide outage, according to the dashboard.

But in an update posted at 7:30 PM GMT, Microsoft said it was “actively recovering Windows Azure hosted services in the North Central U.S., South Central U.S. and North Europe sub-regions,” and that “more and more customers applications should be back up-and-running even if service management functionality is not yet restored.”

As Wednesday wore on, the dashboard reported other outages affecting different aspects of the platform.

The SQL Azure Data Sync service was unavailable in six regions around the U.S., Europe and Asia, and various problems also listed for some regions regarding Access Control 2.0, Azure Reporting, Azure Marketplace and Azure Service Bus.

The notifications promised regular updates on the work fixing the issues, but no concrete timetables.
