O365 CDNs for U.S. Government Community Cloud
Currently it appears that Microsoft O365 CDNs are only available publicly. For those users in the FEDRAMP-compliant O365 GCC, we can't allow data, such as images, to be stored outside of the GCC controlled data centers. However, some of the webparts for SharePoint Online, such as Picture Slide Show, require that images be placed in the public CDN. This isn't acceptable protection for government images. It would be helpful to provide FEDRAMP-compliant CDN options that can work with the GCC.

I think I read somewhere that the Teams provided background images come from a CDN (no idea which one).
We are in GCC and have these background images (they were rolled out to GCC in June 2020).
I can think of 2 possibilities:
1. The O365 CDNs are available to GCC in some areas, but not others (e.g. in Teams, in SharePoint Online Themes but not in SharePoint Slideshow, etc): If that is the case, can Microsoft please publish documentation letting us know WHERE the O365CDN is and is not available in GCC?
2. O365 CDN isn't available in GCC, and some other CDN is providing Teams backgrounds, SharePoint Online Themes, etc: If this is the case, can Microsoft please publish documentation letting us know which CDNs do we have access to in Office in GCC, and where can we utilize them?
