Postmortem: v2 delta generation service experienced failures from ~21:15 UTC Feb 9 to ~10:00 UTC Feb 10, 2026, due to a missing configuration dependency during a logic change.

Impact:

• v2 delta generation requests failed to complete
• No data loss or security impact

Root Cause: Recent logic changes were deployed without the required accompanying configuration update, preventing the service from completing v2 delta requests.

Resolution: The logic changes were rolled back, restoring the service to its previous stable state.

Follow-up Actions:

• Prepare and deploy the permanent fix

We apologize for the disruption and any inconvenience this caused. We are committed to improving our processes to prevent similar issues in the future.

Resolved: This incident has been resolved.

Monitoring: We have identified the potential cause and have rolled back the changes.

Investigating: Some delta generation requests are encountering errors and failing. We are currently investigating this issue.

Postmortem: Balena devices were unable to connect to Cloudlink on February 10, 2026, from approximately 02:26 GMT to 07:11 GMT due to an expired server certificate. Devices that were already connected to Cloudlink were unaffected unless the connection was terminated.

Root Cause: The Cloudlink servers were using an expired certificate that was due for replacement. Consequently, incoming Cloudlink connections failed with a certificate verification error.

Resolution: The certificate has been replaced, and Cloudlink servers were restarted to use the new certificate. Balena devices are expected to reconnect to Cloudlink within a few minutes after being disconnected due to the restart.

Follow-up Actions:

• Expand certificate expiry monitoring coverage to include all active certificates
• Automate the certificate renewal process for Cloudlink

We apologize for any disruption this caused and appreciate your patience as we continue improving our processes and operations.

Resolved: This incident has been resolved.

Monitoring: A fix has been implemented and we are monitoring the results.

Identified: The issue has been identified and a fix is being implemented.

Investigating: We're experiencing an elevated level of errors in our Cloudlink infrastructure and are currently looking into the issue.
