Microsoft: WGA Outage 'Not an Outage'

Microsoft said Tuesday that the glitch that caused Windows Genuine Advantage servers to fail this past weekend was due to human error. According to a post on the WGA blog, pre-production code was released on a production server, causing a domino effect of failures. About 12,000 Windows users were affected. The company said that it did not consider it an outage, since when the servers are down, the system is designed to default to "genuine."

"The production servers had not yet been upgraded with a recent change to enable stronger encryption/decryption of product keys during the activation and validation processes," Microsoft said. "The result of this is that the production servers declined activation and validation requests that should have passed."
