M365 Changelog: Changes to private Content Delivery Networks (CDN)
The current private CDN is moving from being hosted by our 3rd party provider Akamai, to Microsoft Azure. Microsoft Azure CDN is a core service for SharePoint. Microsoft Azure CDN complies with all Microsoft data handling and temporary cache storage standards and as such will be a default feature enabled for all customers.
- Timing: the new private CDN will start rolling out during March 2021 and is expected to be available by June 2021.
- Action: for your information no action required
How this will affect your organization:
Microsoft will automatically enable the new private CDN for your tenant and there is no action required.
If you have already enabled private CDN, or are considering enabling it, then we recommend that you continue to plan to enable the feature as it will immediately benefit your users and optimize your pages. Microsoft will automatically transition existing private CDN configurations from Akamai to Microsoft Azure CDN and no further action is required.
What you need to do to prepare:
You do not need to do anything to prepare.

If you have SharePoint sites that contains highly confidential content that should be specifically excluded from using Azure private CDN, then sensitivity labels can be created and added to the CDN exclusion list. Excluding a site from using private CDN may impact the overall performance of the site since images will no longer use the CDN to optimize the viewing experience.
