This is a postmortem incident report on the outage of our signing service on October 14, 2026.
Major Incident: With non-availbility of CA for signing processes:
Cause: On 14 October 2026, a service disruption occurred during scheduled infrastructure maintenance.
Following an automatic system reboot, some services did not recover as expected,
and the load balancing mechanism did not redirect traffic to the available systems as intended.
The incident was identified and resolved on the same day, and normal service operations were restored.
As a precautionary measure, automatic patching has been temporarily suspended
while we review the underlying causes and implement measures to prevent recurrence.
A incident report will be provided on request.
