   1. Unreliable Signal notification deliveryNotification Sender

      Bắt đầu: 18 Tháng 2, 07:04 UTC

      Thời lượng: 3 days

      We've found a problem with Signal notification delivery: some messages don't get delivered, and trigger a "signal-cli call timed out" error message in the web UI. We are working on a fix.

      Đang xác minh: 20 Tháng 2, 17:59 UTC

      •  Upgraded to the just released signal-cli version (0.10.4), which fixes the reliability problem.
      • Also, added additional logging and alerting on our side, to catch similar issues sooner in the future.

      The issue is resolved.

   1. Degraded performance due to database overloadNotification SenderPing APIDashboard

      At 5:30 UTC, our primary database became overloaded, this caused slow HTTP response times, and notification delays. 

      Khảo sát: 16 Tháng 12, 06:35 UTC

      The database is back to normal currently. The overload seems to have been triggered by a scheduled nightly database backup, but still investigating.

      Our hosting provider is currently performing a backbone connection maintenance. This is causing intermittent latency spikes and connection timeouts.

      The network latency seems to have stabilized but is still higher than usual, and the network maintenance is still underway. The posted maintenance window is 2021-12-15 20:00 UTC+0 – 2021-12-16 15:00 UTC+0.

      The hosting provider has completed the scheduled maintenance (https://status.hetzner.com/incident/b90d7054-17af-4eae-a861-7ea9bfc489db).
      
      The network latency between Frankfurt and Falkenstein is back to normal levels (5ms ICMP ping, 10ms for a complete HTTP request).
