  • Get-GitHubStatus.ps1
  • Get-GitHubScheduledMaintenance.ps1

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• jp.githubstatus.com
  • Triggering command: /usr/bin/pwsh pwsh -Command . ./src/variables/private/StatusBaseURL.ps1 . ./src/functions/private/Utilities/Stack/Get-PSCallStackPath.ps1 . ./src/functions/public/Status/Get-GitHubStatus.ps1 Get-GitHubStatus -Stamp Japan (dns block)
  • Triggering command: /usr/bin/curl curl -I REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_description>## Summary
Add support for the Japan ('jp') region in the GitHub status check functions.

Background

GitHub Enterprise Cloud data residency in Japan is now generally available (announced December 18, 2025). This introduces a new regional status endpoint for Japan-based GitHub Enterprise Cloud customers.

Details

• Japan status page: https://jp.githubstatus.com/
• Main announcement: https://github.blog/changelog/2025-12-18-github-enterprise-cloud-data-residency-in-japan-is-generally-available/

The PSModule/GitHub status check functions should be updated to support the 'jp' region alongside any existing regions, allowing users to check the status of GitHub services in Japan.

Expected Behavior

Users should be able to query the Japan region status using a parameter like -Region jp or similar, which would check the status from https://jp.githubstatus.com/.

References

• GitHub Enterprise Cloud with data residency in Japan allows customers to store their code and repository data in Japan
• This helps customers meet their compliance, regulatory, or data residency needs in the region</issue_description>
