   1. Database server outageEmail DeliveryNotification SenderPing APIDashboard

      Our database server is down. Investigating.

      Post-mortem

      On April 30, starting from 15:46 UTC, Healthchecks.io was unavailable for about 30 minutes. The outage was caused by, most likely, hardware instability on the database server. The PostgreSQL server crashed with a segfault, and a little later, the entire server stopped responding to pings. The system recovered after reboot. Afterward, to reduce the chance of a similar incident in the future, I migrated the database to new hardware.

      Systems are back up after database server reboot. Server logs suggest hardware instability, so we may need to switch do different hardware.

      解決済み: 30 4月, 16:44 UTC

      The systems are back up and working normally.
      
      We have not yet switched database hardware, but will be doing a more thorough analysis in the background.
   2. メンテナンス: Database server upgradeNotification SenderPing APIDashboard

      間隔: 15 4月, 10:00 - 10:20 UTC

      We will be performing a database server upgrade on April 15, 10AM UTC. Expecting about a minute of downtime. During the downtime, pings will be queued and replayed later. API calls and web UI will not work.
