Affecting millions of users globally.
On Friday, November 13, a major cyber event happened after technology giant Microsoft saw a major breakdown across its different services in various parts of the world.
Following the recent threads of the Microsoft 365 Support on the social networking platform X (formerly Twitter), the outage began with the report by users who were experiencing issues accessing Exchange Online mailboxes through multiple connection methods in the Americas, early Friday morning (November 13, Manila time).
At 2:35 am (Manila time), the support team noted that they have determined that a portion of infrastructure was “experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors.”
They redistributed traffic worldwide to help balance the load, with the team later determining that the elevated load was driven by “a number of servers being unexpectedly unavailable; straining the remaining infrastructure.”
Throughout the day, the team worked on recovering and reactivating all its services.
As of the recent posts, as of this writing, the team said that they are already seeing “continued recovery progress across affected regions,” with broader improvements in North America, “sustained improvements” across much of Europe, and “encouraging recovery signals” in Asia Pacific.
“Some users may still experience intermittent access issues or delayed email delivery as mitigation continues across remaining affected infrastructure,” they added.
The team also noted that their focus remains on stabilizing recovered infrastructure, completing mitigation in remaining impacted areas, and reducing delayed email queues and backlogs, while also validating service consistency across connection methods.
It eventually said that they are now “approaching normal levels,” with email queues significantly reduced.
“Some users may still experience intermittent access issues or delayed email delivery as recovery continues,” the company furthered, noting that they have implemented additional mitigation measures, restoring remaining affected infrastructure, and are already investigating residual service issues.
All, while closely monitoring service health and validating recovery across affected connection methods.
