Microsoft is warning developers to update their .NET-related applications and pipelines as two critical domains, “dotnetcli.azureedge.net” and “dotnetbuilds.azureedge.net,” will soon be discontinued due to CDN provider Edgio’s bankruptcy. The domains are expected to be retired in early 2025, potentially affecting various development workflows.
Affected systems include:
- .NET installers
- GitHub Actions
- Azure DevOps custom pipelines
- Docker configurations
- Scripts referencing the old domains
Microsoft recommends developers replace references to azureedge.net and dotnetcli.blob.core.windows.net with builds.dotnet.microsoft.com. During the transition, content delivery will be handled by a combination of Edgio, Akamai, and Azure Front Door.
There’s some confusion around the urgency of the migration, as Microsoft has confirmed ownership of the affected domains and stated that no other parties will have access to them. Despite this, developers are being asked to act quickly, even during the holiday season.
Teams will also need to update their firewall configurations to allow traffic from the new domains (builds.dotnet.microsoft.com and ci.dot.net) and ensure their CI/CD tools are using versions that support the new domains.
A Github page has been created to support developers in the migration.
