Deprecation of 'Use Content Delivery Network' Feature
Completed - The scheduled maintenance has been completed.
Jul 19, 17:00 PDT
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jul 18, 17:00 PDT
Scheduled - We are completing the final phase of the deprecation of the "Use Content Delivery Network" (CDN) feature in Zoom Meetings Web. The UI-side disablement was rolled out last year, and we are now performing a full backend cleanup — removing the remaining codebase and associated database tables.

What Is Changing?

The backend infrastructure supporting the "Use Content Delivery Network" toggle is being permanently removed. This includes:

- Removal of all code related to the CDN feature
- Cleanup of associated database tables

The feature's UI control has already been disabled and was communicated in a prior release. This update completes the full deprecation cycle.

Why Are We Making This Change?

This cleanup effort is designed to reduce technical debt, streamline our codebase, and minimise the risk of future regressions. It is part of our ongoing commitment to maintaining a healthy and efficient platform.

Impact on Administrators

- No disruption is expected. This is a backend-only cleanup with no customer-facing impact.
- No breaking changes or compatibility issues are anticipated.
- No action is required from administrators or end users.

This communication is being sent proactively out of an abundance of caution, in the unlikely event of any minor hiccups during the maintenance window.

Questions or Concerns?

If you have any questions, please reach out to the Zoom support.

Thank you for your continued partnership. We appreciate your patience as we work to keep the platform robust and reliable.
