On the 25/09/2014 between the hours of 20:00 – 22:00 we will be replacing a line card in our LON01-CORE following on from the failure seen on the 28/08/2014.
The works will involve disconnecting all devices that are connected to that line card. Any server that has a redundant feed via another line card will remain online but “at risk” Any server with a single feed will go offline for the duration. Where customer’s PBXs are connected to this line card, they will see a loss of service and may require a reboot of their handsets / system following the works to clear any stale NAT sessions.
UPDATE01 – 20:10
Work on this replacement has started and engineers have started to disconnect devices connected to the S3 line card.
UPDATE02 – 20:50
The card has been replaced and devices have been reconnected. The card is now being placed in to a test mode to complete a series of self tests. Ports may reset and services are still classed as at risk.
UPDATE02 – 22:50
Testing complete and the line card is now back in service. Any users who don’t have a connection to there PBX are advised to power down your hardware and then power back on.
