Describe the bug / error

On a single tenant (so far) - we're seeing NO SPFx web parts loading at all, instead rendering a [object Object] error

I'm seeing CORS errors from the the public-cdn.sharepoint.com - client reports they've seen it for the past few days,

The network request looks like this

GET https://public-cdn.sharepointonline.com/.sharepoint.com/sites/apps/ClientSideAssets/59903278-dd5d-4e9e-bef6-562aae716b8b/modern-search-box-web-part_f7cae02a60fdd9184eb5.js

Stripping the CDN and trying

GET https://.sharepoint.com/sites/apps/ClientSideAssets/59903278-dd5d-4e9e-bef6-562aae716b8b/modern-search-box-web-part_f7cae02a60fdd9184eb5.js

Works just fine, initial thought was that it was related to MC1184996 but as we're seeing ...public-cdn.sharepointonline.... and not ...publiccdn.sharepointonline... I'm pretty sure it's unrelated.

Public CDN is (and was) enabled:

Steps to reproduce

No clue, be on an unfortunate tenant I guess, tenant is set to "Standard Release" and Data Location is "European Union\EFTA"

Expected behavior

Web parts should load
