PMI asm diffs infra failures

The jobs are failing with:

11:55:25 dotnet-install: Downloading link: https://dotnetcli.azureedge.net/dotnet/Sdk/2.1.503/dotnet-sdk-2.1.503-win-x64.zip
11:55:27 dotnet-install: Cannot download: https://dotnetcli.azureedge.net/dotnet/Sdk/2.1.503/dotnet-sdk-2.1.503-win-x64.zip

11:55:29 Could not find/download: ".NET Core SDK" with version = 2.1.503

example.
Other jobs run this command without any issue, for example arm64_cross_checked_windows_nt_innerloop_prtest:

dotnet-install: Downloading link: https://dotnetcli.azureedge.net/dotnet/Sdk/2.1.503/dotnet-sdk-2.1.503-win-x64.zip
dotnet-install: Extracting zip from https://dotnetcli.azureedge.net/dotnet/Sdk/2.1.503/dotnet-sdk-2.1.503-win-x64.zip

Can this link be inaccessible from win2012-* nodes?

Probably this machine win2012-3150b0 is out of space (https://github.com/dotnet/core-eng/issues/6144)
