Microsoft announced that Edgio, a key Azure Content Delivery Network (CDN) provider, will cease operations on January 15, 2025, much earlier than its original commitment to operate until November 2025. This unexpected change results from Edgio’s Chapter 11 bankruptcy and subsequent sale of assets. The shutdown impacts several Azure CDN domains, including those ending in .azureedge.net, which host critical .NET binaries and installers on .azureedge.net, a service used by  Azure DevOps and GitHub Actions.

In September 2024, Edgio filed for Chapter 11 bankruptcy to facilitate the sale of its assets under new ownership. Akamai acquired selected assets, finalizing the transaction in December 2024. As part of this transition, Microsoft was notified that Edgio’s platform would terminate by January 15, 2025, leaving organizations reliant on its services with a narrow window for migration.

The affected domains are primarily .azureedge.net, which host critical .NET binaries, installers, and other resources. These domains are integral to services including Azure DevOps and GitHub Actions, which depend on them for installation and functionality. Without migration, these domains could experience downtime or become permanently unavailable​.

Microsoft has emphasized the importance of migrating these resources to new domains, as continued dependency on Edgio services beyond the shutdown date is not feasible.

Microsoft is working to migrate resources to its Azure Front Door platform. They are collaborating with internal teams to ensure continuity of service, including updating scripts and links to new URLs if disruptions occur.

“Azure DevOps and GitHub Actions installation tools are dependent on some of the resources (mentioned in Q3). We are working directly with those teams to maintain continuity of service. They are moving to the new domains at best speed.” With this work Microsoft will be hoping that there will be limited impact to services.

Microsoft did add however, “there is a chance that the Edgio CDN services will be terminated before we, our partners, and our users have a chance to adapt to the proposed changes in a staged and safe manner. If that happens, we will change existing scripts and links to use the new URLs and CDN immediately. That approach would maintain service for the bulk of users but might break users with firewall rules.”

• January 3, 2025: Profiles on Edgio CDN will be locked.
• January 6, 2025: Automatic migration to Azure Front Door will no longer be supported.
• January 7, 2025: Microsoft will attempt “best effort” migrations for remaining customers, which may involve significant risks.

Note: Automatic migrations are not possible for domains ending in .vo.mcecnd.net.

Yes. Microsoft acknowledged that Edgio’s CDN services may end before all users adapt to the proposed changes. In such a scenario, existing scripts and links will be updated immediately to maintain service for most users. However, this approach may cause issues for users with strict firewall configuration.

Microsoft recommends taking the following immediate actions:
1. Update References: Replace any .azureedge.net domain references with the new domains.
2. Update Local Scripts: Ensure all local scripts point to updated CDN domains.
3. Validate Firewall Rules: Verify that your firewall rules are compatible with Akamai and Azure Front Door CDNs.
4. Monitor Updates: Keep track of Microsoft’s updates via the azureedge tracking issue #9674.
5. Migrate to Azure Front Door: Use Microsoft’s step-by-step migration instructions:
• Azure Front Door Overview
• Migrate Azure CDN from Edgio to Azure Front Door

1. January Change Freezes: Many organizations enforce change freezes during the first week of January, complicating efforts to migrate.
2. Technical Adjustments: Updates to firewall rules, scripts, and domain configurations may require significant IT resources.
3. Limited Support for Late Migrations: Microsoft’s “best effort” migration approach may cause billing, feature, and performance discrepancies​.

Microsoft will attempt to migrate remaining services to Azure Front Door on a “best effort” basis. This process could result in:
• Billing discrepancies.
• Feature and performance limitations.
Businesses using .vo.mcecnd.net domains will not be automatically migrated​

Edgio will undergo an administrative liquidation process to sell its remaining assets. Customers should discuss with their account managers to understand if and when they may receive any compensation.
