Microsoft-ын Outlook, Teams-ийн саатлыг засах оролдлого хүлээсэн үр дүнд хүрсэнгүй

Major Microsoft services, including Outlook, Teams, and Microsoft 365, experienced widespread outages affecting thousands of users, as the tech giant said its changes are “not taking as expected”.

“We’ve monitored the status of the changes applied to improve serviceability and confirmed they’re not taking as expected,” Microsoft wrote on X on Friday.

“We’re continuing to monitor the results of changes applied so we can identify strategic actions that can help to improve service health across all affected regions,” the software giant said in its latest update.

The disruption extended to integration connectors used by AI providers OpenAI and Anthropic.

Almost 130,000 users reported problems accessing Outlook just after 1.00pm ET on outage tracker Downdetector, a website that tracks outages by aggregating status reports from several sources.

Reports have since fallen somewhat, but many users said they still couldn’t send and receive emails or had trouble loading their inboxes altogether.

Downdetector also recorded more than 38,000 user reports concerning problems with Microsoft 365, alongside roughly 4,500 reports of users encountering difficulties accessing Teams.

“We’re aggressively pursuing all pathways to reduce impact,” Microsoft said in an earlier statement.

The company said that its team paused all deployments and was routing additional traffic away from the affected infrastructure while restarting impacted servers to bring them back into service.

“We’re actively restarting and validating the affected servers to return them to service. In parallel, we’re assessing whether reverting a small number of recent configuration updates we identified could help accelerate recovery,” the company wrote in its update on X.

“The servers we returned to service can become unresponsive again once they receive traffic; we’re analysing diagnostic data to determine what’s triggering the behaviour,” it said.

Microsoft said in an initial post hours earlier that it determined “a portion of infrastructure is experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors.”

“We determined the elevated load isn’t driven by an increase in traffic, but by a number of servers being unexpectedly unavailable, straining the remaining infrastructure. We’re working to safely return them to service,” the company wrote in a follow-up post.

Another update at 2.50pm ET read, “We’re testing a configuration change to address a problem that’s causing servers to fail automated health checks and become unavailable. In parallel, we’ve initiated a restart of all affected servers and are monitoring health as they return to service.”

“We’ve not identified any recent change correlated with the start of impact; however, our investigation indicates the failed health checks may originate from a specific component that’s responsible for processing server health. We’ve taken steps to prevent additional servers from being impacted while we work to return the affected servers to service,” Microsoft said in another update.

“We’ve validated an alternative service health check method, which allowed a subset of affected servers to successfully return to service. We’re now applying this change more broadly. We’re also preparing automated recovery systems to continually detect and restart unresponsive servers, to maintain service stability while this change progresses,” the company later wrote.

Microsoft said earlier in the day that it had fixed a Teams disruption affecting users in North America and that the issue was fully resolved. However, the business later noted that the problem could also impact Microsoft 365 service connectivity for users in other regions.

OpenAI said it was investigating an issue involving Microsoft connectors where new connections may break, and tools do not function as expected.

Anthropic said it had identified an issue with an upstream provider that was affecting its Microsoft 365 connector.
