azureedge.net URLs will stop working on 15 January and thus installing Edge will break

[Piedone]

Description

This is really urgent so will need to be quick: see https://github.com/actions/setup-dotnet/releases/tag/v4.2.0 for the larger context, but the gist of it is that azureedge.net URLs will stop working on the 15th of January, possibly sooner. Thus, these scripts will stop working: https://github.com/search?q=repo%3Aactions%2Frunner-images%20azureedge.net&type=code

Looking for alternative URL to download but was not able to.
Raised an issue with the edge-driver repository.
Awaited info..

As crazy as it sounds, this isn't likely to be an issue. In addition to being used by Edgio, the azureedge.net domain is also used by Microsoft's Standard CDN and this is good until 2027. The only way you can tell which CDN provider is being used is by looking at the headers. The Microsoft one has an x-ms-request-id header, whereas the Edgio ones have x-edgio-request-id in them.

Simple eh? 😉 (and someone should have probably given the dotnet team that information too, as it looks like they're not even using Edgio...!)

Edit: would appear that information isn't quite correct. The x-ms-request-id header is coming from blob storage, not from the CDN. Doing some more digging.

Edit2: Best I can come up with is DNS checking, but I don't know how accurate that is. If you nslookup the domain and it resolves to v0cdn.net then it's Edgio, and t-msedge.net is Microsoft. I'm basing this on our own resources (but sadly we deleted the last of our Edgio resources last week so I only have some logs and screenshots to go on)
