This maintenance window consists of the works originally scheduled for the “26-03-2015 – 20:00 – 20:05” That where suspended.
Original notice from the 26th:
We will be shutting down our Frontier interconnect in preparation of moving the circuit from our current legacy access device to CORE01 as part of our ongoing network upgrade works. The circuit will be physically moved on the 07/04/2015 while and engineer is on site and bought back in to service that evening outside of hours.
Call traffic will be routed away from this interconnect several hours prior to the works, However any calls still active on this link will drop once disconnected. Routing to Frontier will then be via one of our indirect peers after the disconnection. No further impact is expected after this.
Further to these works we will also now be moving our Zen interconnect from our current legacy access device to CORE02 in-line with the same ongoing network upgrade works. Any traffic that comes in to us via Zen will see a short 30 second outage while our routing tables update to reflect the removal. Traffic will then flow via one of our indirect peers after the disconnection. This link will be bought back in to service along side our Frontier link.
We apologize for any inconvenience caused.
UPDATE 01 – 20:07
Engineers have shut down both peers and traffic has re-converged without further incident.
