Download of Private.SourceBuilt.Artifacts in prep-source-build terribly slow locally

Might be a CDN thing here in Europe?

It also tries to download from builds.dotnet.microsoft first.

This seems more appropriate to be logged for the dnceng repo.

[ViktorHofer]

OK, happy to move. Is builds.dotnet.microsoft.com the right URL or is that the one that got turned-off?

[mthalman]

Yes, both of those are correct domains. See dotnet/announcements#336
