Scheduled Maintenance Report for Exonet

Postmortem

Date: 11-11-2025

Duration: 1h 38m

Impact: Multiple servers unavailable

Summary

On November 11, 2025, multiple servers were partially or fully unavailable between 00:56 and 02:34. The outage occurred during scheduled maintenance that was intended to be non-disruptive.

Root Cause

The planned failover during network maintenance took longer than anticipated, causing servers to lose access to the underlying storage and became unavailable.

Resolution

The maintenance was aborted and the servers were restarted, after which services were restored. To prevent similar disruptions during future maintenance, a thorough investigation of the failover process was conducted together with our vendor. Based on the findings, network configurations and upgrade procedures have been adjusted.
