Major outage

Incident Report for Sympa

Postmortem

What happened

We experienced a short service impact related to a certificate update. During the update process, the system temporarily referenced an incorrect certificate version, which caused connection issues.

Why it happened

While updating certificates, the platform briefly attempted to use an incorrect certificate version due to internal caching behavior. Even though the correct certificate was already in place, the system continued referencing the outdated one for a short time.

What we did

We identified the issue as soon as it became visible.

The correct certificate was re-applied and verified.

Normal service was restored immediately after this change.
