Need easy access to PowerShell Gallery DNS URLs

[ghost]

When any of the URLs for accessing the PowerShell Gallery change, some users are unable to access it due to firewall restrictions. This came up in the Sept 2018 update. Copying from a Gallery blog comment:

packages will be downloaded from psg-prod-eastus.azureedge.net instead of devopsgallerystorage.blob.core.windows.net,
Is there any chance to get the DNS names somewhere documented? Some companies with url access restrictions would be happy about this

We need to exclude this url in our proxy and firewall configuration. Currently in our dev environment we have exclusions for docker, .net core, npm, nuget and powershell. And with a change occurring every week or so it gets somehow frustrating to debug it every time.

Possible Solution

We should pre-announce when the URLs for the Gallery are changing, or new ones are made available.
In addition, recommended solution would be to document the URLs somewhere, such as in a file in GH that contains the direct access URLs in an easily used format.

If your environment would benefit from this, please upvote or comment.

Would another possible solution be to create friendly DNS name that just CNames to wherever you move it to? something like packages.powershellgallery.com that resolves to devopsgallerystorage.blob.core.windows.net without ever exposing the internal names to the client directly.

+1 to @KevinMarquette idea.

My work environment limits internet access for accounts that have admin rights but exceptions can be made for package URLs.

The DNS names listed above are the only ones we expect to use for now. It is a good idea to whitelist both psg-prod-eastus.azureedge.net and devopsgallerystorage.blob.core.windows.net - one is CDN, the other is storage account. If we need to extend further we will aim to adopt Kevin's proposal (see above) before adding other names, so allowing access to *.powershellgallery.com would be a good idea to future-proof access.
