This is an incident notification regarding VoIP UK voice services. Date: Wednesday, 2nd November 2016 Start time: 15:14 GMT (UTC+0000) End time: 15:47 GMT (UTC+0000) Services affected: IP voice services using VoIP UK. BT services were unaffected. Report: Comtec NOC observed a drop in all registrations and an inability to register with VoIP UK. We have received the root cause analysis and remedial action from our vendor as follows: "We have experienced a service affecting problem as documented above. Our network operations team tracked and repaired. More than one customer region was affected and as such our customer support lines were very busy during and shortly after the time window above. Symptoms Customers may have experienced problems dialling out and may not have been able to receive calls. Most customer systems self-repaired, however it may have been necessary to restart some customer based equipment to bring back into service. Technical A customer programmatic event causing a system loop prevented normal fast database access. As a result outbound calls failed to be authorised in a timely manner and inbound calls may have been blocked for some customers. The immediate cause was identified, removed and remedial action was taken to bring stressed network components back in to normal operation. Further to this a development case has been raised to prevent a re-occurrence." Comtec NOC was tracking this issue under ticket [#DCX-370-12304]. This is the final update. Regards, David Croft | |
