We have scheduled an emergency maintenance for tonight at 22:00 PM , on one side of our core network infrastructure. This is a premptive action to remediate the recent power issues we have had on the A-side breaker and to ensure we have full resilience on the core network should the issue re-occur . We are undertaking this as an interim measure until we can arrange a full shutdown in order to change the breakers.
We will be moving access and core switches and firewalls to an ATS (automatic transfer switch ) which will maintain power in the event of a breaker outage on any single powered device.
This will involve a clean shutdown/ reboot of the device. Traffic will be rerouted on the B-side of the network infrastructure and there may be a minor outage (2-3 pings ) whilst traffic reconverges.
