Which CDN is Teams GCC using?
I know the Teams provided background images come from a static CDN endpoint.
The O365 CDNs are not available to GCC, however, per this article:
https://docs.microsoft.com/en-us/office365/enterprise/use-office-365-cdn-with-spo (updated Feb 19, 2020)
Therefore, I want to know which CDN(s) does Teams use in GCC?
Which CDNs are providing the Teams backgrounds, and which other ones are in use elsewhere in GCC?
