## Timeline of updates

- **scheduled** 2026-10-19 09:19 UTC: We're upgrading our CI infrastructure to improve reliability and security. Expected impact: - Brief connectivity blips as we migrate outbound traffic. - Builds running during the migration may fail on outbound calls (git clone, artifact pulls, webhooks) and will need a re-run. - Re-runs will succeed once the migration completes. Your action: If you haven't already allowlisted the new egress IP ranges (8.235.0.0/24 and 34.33.12.0/24), please do so now.
- **in progress** 2026-10-24 05:36 UTC: Scheduled maintenance is currently in progress. We will provide updates as necessary.
- **verifying** 2026-10-24 06:20 UTC: Verification is currently underway for the maintenance items.
- **completed** 2026-10-24 06:32 UTC: The scheduled maintenance has been completed.
