Microsoft has issued a critical advisory to .NET developers regarding the transition from Edgio-hosted domains. Edgio, formerly known as Limelight, has filed for bankruptcy, leading to the shutdown of its Azure Content Delivery Network (CDN) services. This change necessitates immediate updates to installation links to prevent service disruptions.

Background

Historically, Microsoft utilized Edgio's CDN to host .NET binaries and installers on domains such as INLINECODE0 and INLINECODE1 . With Edgio's impending shutdown, these domains will become unavailable, potentially causing significant disruptions for developers relying on them. (thehackernews.com)

Implications and Impact

The cessation of Edgio's services means that any applications, scripts, or CI/CD pipelines referencing the affected domains will fail to retrieve necessary .NET components. This could lead to build failures, deployment issues, and overall service downtime. Developers must act promptly to update their configurations to ensure uninterrupted operations.

Technical Details

Microsoft recommends replacing references to the outdated domains with the new official domain: INLINECODE2 . This change involves updating codebases, scripts, and pipeline configurations to point to the new domain. Additionally, developers should verify that their firewall and network configurations allow traffic to the new domain to prevent connectivity issues. (bleepingcomputer.com)

Recommended Actions

  1. Audit and Update References: Search your codebase, scripts, and configurations for any references to INLINECODE3 and INLINECODE4 . Replace them with INLINECODE5 .
  2. Update CI/CD Pipelines: Ensure that your continuous integration and deployment pipelines are configured to use the new domain. This includes updating any actions or tasks that fetch .NET components.
  3. Test and Validate: After making the necessary updates, thoroughly test your applications and pipelines to confirm that they function correctly with the new domain.
  4. Monitor for Issues: Keep an eye on your systems for any anomalies or errors that may arise due to the transition. Promptly address any issues to maintain service reliability.

Conclusion

The transition from Edgio-hosted domains is a critical change for .NET developers. By proactively updating your configurations and ensuring compatibility with the new domain, you can avoid potential disruptions and maintain the stability of your development and production environments.
