**RFO – Wednesday 31st December** At **13:39**, our primary service provider experienced extremely high latency on the connections supplying our network. While this caused service degradation, the connections did not go fully offline, which prevented automatic disaster recovery from initiating.

By **14:35**, all services were fully restored and operating normally..
