Some inbound telephone numbers are unreachable

Incident Report for CM.com

Postmortem

A database change at one of our suppliers resulted in some numbers not being routed anymore. The net result was that calls to these numbers never arrived at our platform, hence our monitoring could not “see” these failed calls.

Our supplier has reverted the change and checked the affected numbers. We have also tested these and found no other issues. We have monitored the traffic together with our supplier and found no further issues.

Update

The latest update is that the change has been rolled back at our supplier. All numbers should be fully operational. We will continue monitoring.

Update

We now have a work-around in place. This work-around works on a per-number basis, until our supplier can find and solve the actual issue, so please inform us if you have any issues receiving phone calls on a number hosted with us.
