Root cause

The incident was due to a load increase on our firewall (in front of Cloudi-fi Services). Because of this load, services (Admin Console, Captive portal) were not working properly. This sudden increase is caused by malicious requests.

 

Impact

The Admin Console and captive portal are functioning partially.
