Microsoft Explains Recent Hotmail Outage

Maximum PC Staff

Hotmail may been losing some of its “geek cred” to more feature rich services such as Gmail, but as one of the most popular email providers in the world, they had a bit of explaining to do after accidentally wiping out the inboxes of over 17,000 users last week. According to Microsoft’s Mike Schackwitz, an error in a script that is used for testing the stability of the service accidentally deleted valid user account folders, rather than just those belonging to internal test bots.

"In Hotmail, one way we monitor the health of the e-mail service is through automated tests. We set up a number of accounts with different configurations, and then use automated tests to log into these accounts, simulate normal user activity and behavior, and report when errors are found," Schackwitz wrote in a blog post. "We use scripts to create and delete these test accounts in bulk. The way we delete a test account is to remove its record from a group of directory servers that route users and incoming mail to the correct mailbox."

Microsoft didn’t really apologize for the error in its blog post , but at least they claim to have learned a valuable lesson. "This issue was one that had not arisen before, and at first, we did not assign it to the correct team for action," Schackwitz wrote. "Additionally, because there were a relatively small number of reports, the volume wasn't high enough to set off alarms. This meant we had a ticket in the system that was getting no action."

Microsoft has restored all missing emails but has this further eroded your trust in Hotmail?
