openSUSE:Post-mortem-20240516

• What/Problem: openSUSE forum service was disfunctional
• When: 2024-05-16 01:43 to 04:57 UTC
• Why: We identified a number of contributing issues:
  • autoupdates run at night when nobody is around to fix breakages
  • discourse-update failed in the MaxMind (GeoIP) database update step, which caused puma to remain stopped "Job discourse-puma.service/start failed with result 'dependency'."
    • => caused by MaxMind now requiring redirects, solved in new Discourse release: https://github.com/discourse/discourse/commit/e70fa2df6fe5d1c37719b5b212f38041d3d72db5
    • => patch to furthermore handle such conditions gracefully: https://github.com/discourse/discourse/pull/27048
