Expert says Microsoft outage is unusually large and prolonged

Cybersecurity expert Petteri Järvinen told Yle he cannot recall a disruption to Microsoft’s services that was as large and prolonged as the current one.

Microsoft said, according to the BBC, that it had made “marginal progress” in addressing the problem. The company attributed connection issues to heavier-than-usual load on its infrastructure.

Järvinen believes Microsoft tried to resolve the issue by restarting its machines. He said it was surprising if that had not helped, suggesting there may be a larger problem.

Yle has confirmed that users in Finland are also experiencing problems with Microsoft services, but their overall extent is not known.
