Outlook.com is suffering a series of outages today after being down multiple times yesterday, with hacktivists known as Anonymous Sudan claiming to perform DDoS attacks on the service.
This outage follows two major outages yesterday, creating widespread disruptions for global Outlook users, preventing users worldwide from reliably accessing or sending email and using the mobile Outlook app.
Microsoft says these outages are caused by a technical issue, posting to Twitter a series of updates switching between saying they mitigated the issues and saying that the problem is happening again.
While Microsoft claims technical issues cause the outages, a group known as Anonymous Sudan is claiming to be behind them, warning that they are performing DDoS attacks on Microsoft to protest the US getting involved in Sudanese internal affairs.
The group has been taunting Microsoft in statements about the repeated DDoS attacks on Microsoft Outlook and Microsoft 365 services.
While these claims remain unverified, the service has been sluggish and plagued by a series of outages over the past 24 hours.
