Office CDN Returning “GatewayExceptionResponse” for All Installer URLs

The Microsoft Office CDN at officecdn.microsoft.com is currently returning a “GatewayExceptionResponse” for all HTTPS requests, including the root domain. This affects multiple devices (MacBook Pro and iPhone) and multiple browsers (Safari and Chrome). Examples:
https://officecdn.microsoft.com/

https://officecdn.microsoft.com/pr/wsus/ofmac/OfficeMac/OfficeMac_Installer.pkg

https://officecdn.microsoft.com/db/OfficeMac/OfficeMac_Standard_2021.pkg

DNS resolution is working (ping returns continuous replies), but all browser requests fail instantly. This appears to be a Microsoft CDN gateway outage or misconfiguration affecting my region. Can this be escalated to the Office CDN engineering team?

    The complete service outage has persisted for at least 9 days.

    This is a Microsoft CDN gateway outage affecting all Office 2021 for Mac installer URLs. This requires engineering escalation, not user‑side troubleshooting.

    This outrage has persisted for at least 24 hours.

    seems to be outside of Microsoft’s defined measures of quality (DMoQ).

    It seems you are experiencing issues with the Microsoft Office CDN, specifically with receiving a "GatewayExceptionResponse" for all HTTPS requests. This could indeed indicate a temporary outage or misconfiguration affecting the CDN in your region. Unfortunately, I cannot directly escalate issues to the Office CDN engineering team. However, you might consider checking the Microsoft 365 service health dashboard for any reported outages or issues that could be affecting the CDN services. Additionally, reaching out to Microsoft Support may provide you with more immediate assistance regarding this matter.
