Summary

The 2026-10-30 daily remote tests failed with:

The published IP ranges of GitHub are unavailable for the rest of this run, ... HTTPError: 403 Client Error: rate limit exceeded for url: https://api.github.com/meta

The GitHub API allows 60 unauthenticated requests an hour per IP address. Hosted runners share their addresses, so the allowance is often spent before our job asks. The two Azure tests from #329 passed in that run. Only the GitHub listing failed, in test_every_published_listing_is_available_remote and test_resolver_resolves_public_ip_remote.

Changes

• _request_published_listing now sends Authorization: Bearer <token> when GITHUB_TOKEN is set and not blank.
  • It only does so when the request's host is exactly api.github.com. The token never goes to AWS, GCP, Microsoft or the VPN listing.
  • Without the variable, requests are unchanged.
• .github/workflows/remote_testing.yml sets GITHUB_TOKEN: ${{ github.token }}. That is the job's built-in token, which raises the limit to 1,000 requests an hour per repository. No new secret and no extra permissions are needed.
• README: one sentence on the optional GITHUB_TOKEN.

Production on Typhon is unlikely to hit this. Typhon fetches about once per run from its own address, and since #329 a saved copy stands in if the GitHub listing is ever refused.

Tests

• The fake requests.get in tests/test_service_networks.py now records the headers of each request.
• New test_github_token_is_sent_to_the_github_api_only covers the variable unset, blank, and set. It checks the header reaches api.github.com/meta only when set, and that every other request is sent with no headers.
• pytest tests -m "not remote": 471 passed. pre-commit run --all-files: clean.
• The remote job on this PR runs with the token, so it exercises the authenticated request.

Version 1.16.0 → 1.16.1.
