- postmortem Feb 10, 2026, 11:52 AM UTC
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.
