Breaking News for .NET Developers: Update Your Infrastructure Now!

.NET developers, listen up! Microsoft is making a significant change to the way .NET installers and archives are distributed, and it requires immediate action to avoid disruption.

Microsoft is migrating .NET installers and archives away from Azure Content Delivery Network (CDN) domains hosted on Edgio (.azureedge[.]net) due to Edgio’s platform shutdown on January 15, 2025. The company will automatically migrate most users to Azure Front Door CDNs by January 7, 2025. However, manual intervention is required for specific scenarios.

What Undercode Says:

This change, while unexpected, is necessary to ensure the continued availability and security of .NET deployments. Here’s a breakdown of the situation and what you need to do:

Impact: Most developers will be unaffected. However, those using custom domains (.vo.msecnd.net) or planning to migrate to a non-Microsoft CDN provider need to take manual action.

Action Required:

Check if your infrastructure relies on .azureedge[.]net domains.

If using custom domains (.vo.msecnd.net), migrate them before January 7th to avoid automatic migration to Azure Front Door.
If migrating to another CDN provider, set the “DoNotForceMigrateEdgioCDNProfiles” feature flag before January 7th.

Important Dates:

Automatic migration to Azure Front Door by January 7, 2025 (unless manual intervention is applied).
Azure CDN configuration changes via Edgio profiles disabled after January 3, 2025.

Edgio platform shutdown on January 15, 2025.

Alternative CDN migration deadline: January 14, 2025.

Recommendations:

Consider adopting a custom domain for better control and redundancy.
Update codebase references from .azureedge[.]net to the new URLs provided by Microsoft (builds.dotnet.microsoft.com).

Analysis

Microsoft’s decision to migrate away from Edgio-based CDNs is a prudent one. Edgio’s shutdown poses a potential risk to the availability and security of .NET deployments. While automatic migration to Azure Front Door offers a convenient solution for most users, it’s crucial to be aware of the exceptions and take necessary steps to avoid disruptions.
