Core Network Switch Upgrade And Firewall Move

Message

On the 11th of June we will be completing the upgrade of the core access switches in Interxion. As part of this, we need to physically move the current shared firewalls in Interxion to a different position within the rack. As they are a HA pair, it should be possible to do this without affecting connectivity.

The time line will be as follows:

02:00 Fail-over all the traffic to the second firewall in the pair. Once we're sure traffic is flowing through the second firewall, power down, move it to it's new position in the rack and recable. Power it back up and ensure that it's working as expected.

02:30 Repeat the procedure with the second firewall in the pair.

03:00 Install the new switches, and start swapping over from the current switches. There should be minimal downtime involved with this as each customer and rack switch has redundant connectivity back to the core.

The maintenance window will end at 06:00 once we're sure that every thing is back up and running as expected.

UPDATE Jun 12th 06:00 This maintenance window has now completed. Unfortunately not everything was completed, but the main work of moving the firewalls and getting the new switches in has been done. The few bit remaining will be completed during a future maintenance window.
