11/10/2024 09:10:00 AM

NHSmail Reference: INC46177388

Microsoft Reference: MO907640

Issue Status: RESOLVED

Issue Description: Admins may be unable to access the config.office.com web page.

More Information: Affected admins may see the page not loading and “ERR_CONNECTION_TIMED_OUT” errors.

Current Update: 21/10/2024 09:10:00 AM After further evaluation, Microsoft have opted to allocate additional resource capacity in both the US and EU regions to help process requests. Once the resource capacity was functional, they monitored their telemetry to validate the the errors were no longer occurring and that the impact was remediated.

Scope of impact: This issue can potentially impact any admin who’s served through the affected infrastructure and attempting to access the config.office.com web page.

Root cause: A traffic management misconfiguration is causing a section of infrastructure, responsible for facilitating the config.office.com web page, to operate below acceptable performance thresholds.

Next Steps: Microsoft are continuing to analyze the impacted section of infrastructure to gain further insight into what triggered the errors, which will help us prevent similar impact in the future.
