General communicate service [SEWAN] Unexpected disturbances - 16.04.2025

Beginning: 16.04.2025 – 11.44 AM

Ending: 16.04.2025 – 11.54 AM

Impact: Sip trunk unregistered at 11.44AM.

 

Dear customer, dear partner,

 

Please note that there is an ongoing network issue at our backhaul level. We suspect a ping in LAN that is loosing packages.

keepalived backup got confused by that, and did an automatic master/slave switch on DB cluster, forcing a switchover for safety reasons.

This caused a 3 to 10 minutes deregistration of Sip Trunks.

The situation is under control. Our VoIP team is now analyzing the root cause of the network issue.

 

No intervention is need from your side.
