We are aware of a problem with one of our media gateways affecting inbound and outbound calls. We are currently investigating as a matter of priority.
UPDATE01 – 13:13
Engineers have found the media gateway to be suffering from a sudden high CPU load. We have been able to stabilize the system remotely and are currently monitoring.
UPDATE02 – 13:20
We have seen a repeat of high CPU demand and are in the process of isolating the service.
UPDATE03 – 13:25
The service has been found and the root fault isolated with remedial works planned over the weekend. We apologies for the issues caused.
Additional media gateways had already been planned for deployment over December to provide additional redundancy, this will now be bought forward.
UPDATE04 – 15:00
We are still seeing some calls fail to route due to stuck sessions on customer trunks. This was caused by the SQL service being overloaded and log entry’s being missed. Work is being planned for tonight to reload the affected services.
UPDATE05 – 20:00
Work has been undertaken to stabilise the platform.
UPDATE06 – 21/11/2016 12:00
Engineers have completed the install of additional hardware and a migration plan will be designed in due course.
