Due to a yet unidentified certificate/authentication error, several IRC services are currently unavailable. Investigating.
07:33 Working as expected ; closing incident.
21:35 Never letting a good crisis go to waste, we took the opportunity to upgrade both server & service to the latest version. Monitoring.
12:04 The issue has been temporarily mitigated. During the day, some reboots may be required, causing temporary authentication (= login) failures.
09:43 root cause appears to be issues with CA certificate verification at the LDAP authentication server ; continuing investigation.
