Incident Report for CM.com

Postmortem

We hereby update you with an official RCA (Root Cause Analysis) regarding the reported issues with outbound calls to Dutch (+31) numbers.

At this moment, all traffic has been restored to regular quality standards and customer expectations.

Date & time:

Start: Monday July 8th, 06:30

End: Tuesday, July 9th, 14:30

Reported issue(s):

One-way audio
Robotic voices
Increased call setup times, resulting in an increase of cancelled calls
Increased % of failed calls

Root cause:

The cross-connection in our Amsterdam datacenter with our primary carrier for NL (+31) traffic was malfunctioning.

This caused the reported issues to occur for a majority of the traffic to NL numbers.
All traffic to NL numbers was routed to secondary carriers. Due to insufficient capacity at some of these secondary carriers, an increase of failed and cancelled calls occurred.

Measures taken:

Replaced faulty cross-connect, enabling us to reinstate routing for primary carrier
Requested capacity upgrade with secondary carriers
Initiated interconnect with 2 additional carriers
Added additional monitoring and alerting tools regarding carrier capacity

If you have any further questions and/or are still experiencing issues, please do not hesitate to contact us via support@cm.nl

Resolved

We have identified the cause to be with one of our primary interconnects for NL (+31) outbound traffic. Until further notice this carrier has been disabled and traffic is being routed through our other carriers. An official RCA via e-mail will follow to all clients that were affected by the quality disturbance. In case you still experience issues with calls through one of our platforms, please contact our Support department or your account manager.
