EasyIPT – VoIP Calls – Outbound OFFNET – 10:50 18/05/2014 *RESOLVED*

We are aware of a problem with an upstream provider that is preventing the termination of OFFNET (Mobile, Local, National and international) calls. We are currently working to resolve the fault and will provide updates shortly.

UPDATE01 – 11:36
Local and national calls should now be terminating correctly, however mobile calls are still resulting in a BUSY response from our carrier.

UPDATE02 – 12:00
Mobile and international calls are now terminating correctly.

We have logged a case with the carrier for details and will provide this once made available.

We apologise for any inconvenience caused

UPDATE03 – 12:24
We have been advised the root cause of the failure was “a major outage on the BT IP exchange interconnect which caused a high proportion of calls to fail.”

In light of this outage, Structured Communications will be implementing carrier diverse outbound routing. This will require large network changes and further details to follow in the coming weeks.

LON01 – BGP Update – 20:30 – 06/05/2014 *COMPLETE*

In preparation of our new transit and private 1Gbps interconnect to Zen Internet we will be removing all static routes for 3rd party providers and completing a fail-over test prior to the interconnect going live. Once the circuit is handed over to Structured Communications we will create a further out of hour’s maintenance window to bring up the session and complete further checks.

Where a client connects to us via a 3rd party connection not managed by Structured Communications, you will see your traffic revert back to normal paths via Level3 / Adapt.

Due to future network planning and peering we have withdrawn the policy of using static routes.

The above works are expected to take around 10-15 minutes and 2 x 30 seconds blips may be seen while traffic re-converges over our other upstream links.

UPDATE01 – 20:45
Work Complete. No outages where seen.
