NXDOMAIN results for the psg-prod-eastus.azureedge.net domain are breaking package downloads

Start by reviewing the reported failures in PowerShellGet’s package download flow and the PowerShell Gallery endpoints named in the issue, especially psg-prod-eastus.azureedge.net. The report shows intermittent DNS resolution failures across GitHub hosted runners and two public resolvers, but does not identify a project file or test to change. Done means package downloads succeed reliably when the reported endpoint is queried.

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

Install any module.
Install-Module AWS.Tools.ECR-Verbose
Occasionally you will get a failure to download the package.

Expected behavior

PS> $ErrorView = 'DetailedView'
PS> $requiredModules = @("AWS.Tools.Common", "AWS.Tools.ECR")
PS> $requiredModules | Foreach-Object {
    Write-Host "Installing PowerShell Module '$module'"
    Install-Module -Name $module -Force -Verbose
}

Both modules install successfully.

Actual behavior

PS> $ErrorView = 'DetailedView'
PS> $requiredModules = @("AWS.Tools.Common", "AWS.Tools.ECR")
PS> $requiredModules | Foreach-Object {
    Write-Host "Installing PowerShell Module '$module'"
    Install-Module -Name $module -Force -Verbose
}

One occasionally fails, sometimes the first, sometimes the second.

Error details

PS> $ErrorView = 'DetailedView'
PS> $requiredModules = @("AWS.Tools.Common", "AWS.Tools.ECR")
PS> $requiredModules | Foreach-Object {
    Write-Host "Installing PowerShell Module '$module'"
    Install-Module -Name $module -Force -Verbose
}

Environment data

I've had this occur in github actions on github hosted runners and can see the domain name failing to resolve
periodically from our office in New Zealand.

Version

Multiple versions (one is 7.4.6)

Visuals

With verbose output while installing the modules you can see the domain resolution failures:

I wrote a crappy script to check all the domains I could find listed that are required for psgallery package search and downloads and the eastus is the only one failing to resolve. It's failing to resolve from multiple DNS servers (I used google and cloudflare in this test):

# Crappy script to check all psgallery domains
$domains = @("psg-prod-eastus.azureedge.net", "psg-prod-centralus.azureedge.net", "onegetcdn.azureedge.net", "az818661.vo.msecnd.net", "powershellgallery.azureedge.net")
$resolvers = @("8.8.8.8", "1.1.1.1")

while ($true) {
  Start-Sleep -Seconds 1
  foreach ($resolver in $resolvers) {
    $results = [ordered]@{}
    foreach($domain in $domains) {
      $results[$domain] = $false
      try {
        Resolve-DnsName -Name $domain -Server $resolver -ErrorAction Stop | Out-Null
        $results[$domain] = $true
      } catch {
        if ($_.Exception.Message -notlike "*name does not exist*") {
          throw
        }
      }
    }
    Write-Host "$resolver > " -NoNewline
    $results.GetEnumerator() | ForEach-Object {
      $color = ($false -eq $_.Value) ? "Red" : "Green"
      Write-Host -ForegroundColor $color -Message $_.Name -NoNewline
      Write-Host ", " -NoNewline
    }
    Write-Host ""
  }
}
