Our monitoring system indicates a complete outage of the Aruba Wi-Fi system. We are still investigating the cause of the problem.

Update 09:35

Failover to another master node seems to have solved the problem. The system indicates that clients and APs are connected as usual.

Conclusion

We weren't able to notice an impact on the connectivity for users. Only the master nodes responsible for management was hung up. A reboot solved this issue without any further problems.
