Microsoft is investigating an ongoing outage that is preventing OneDrive customers from accessing the cloud file hosting service worldwide, just as a threat actor known as 'Anonymous Sudan' claims to be DDoSing the service.
"We've reviewing OneDrive telemetry that captures this impact scenario to determine the source of the service access failures and begin identifying a mitigation plan."
They also said they took down a number of Microsoft services earlier this week in distributed denial-of-service attacks.
Today's incident follows another lengthy outage from earlier this week that impacted multiple Microsoft services and features, including Outlook, SharePoint Online, and OneDrive for Business.
The outage started Monday evening and was eventually addressed in the early hours of Wednesday, and it was also claimed by Anonymous Sudan as being the result of their DDoS attacks.
BleepingComputer reached out to Microsoft on Tuesday regarding Anonymous Sudan's claims, but we are yet to receive a reply to our questions.
