   1. Signal notification delivery brokenNotification Sender

      Durasi: 17 jam, 46 menit

      We are currently investigating an issue with the delivery of Signal notifications.

      Terselesaikan: 2 Apr, 07:16 UTC

      The problem has been fixed, Signal notifications are being delivered again.
      
      What happened:
      
      On April 1, 13:30 UTC, our signal account became unregistered. This was caused by a new Signal protocol feature – SPQR (Sparse Post-Quantum Ratchet) – becoming mandatory and our Signal client software not supporting it.
      
      The fix:
      
      Updated to the latest signal-cli version (0.14.1), registered a new account with the same old number, and re-added the linked devices.
      
      For more background information, here is an issue on the signal-cli issue tracker discussing the account de-registrations on April 1.
