During the above window we will be performing a rack migration of the Interxion DSL platform. This is a service impacting maintenance. 

At the start of the maintenance window, sessions connected to the Interxion side of the platform will be forcibly disconnected and will allowed to reconnect to the Telehouse infrastructure for the duration of the work. Once the rack migration has been completed, sessions will be rebalanced across the platform by performing additional disconnections from the Telehouse side.

This work is required in preparation to work our Datacenter supplier is carrying out to replace the CRAC units at this location https://noc.enta.net/2024/03/planned-work-interxion-datacenter-lon1-crac-unit-replacement/

For the avoidance of doubt, all DSL services connected to the Interxion side of the platform at the start of the window will experience a brief outage while sessions are torn down and reconnect. All services connected to the Telehouse side of the platform may experience a brief outage towards the end of the window when rebalancing occurs.

We apologise for any inconvenience this may cause.

During the above window we will be performing works on our DSL core within this location. This is a “dry run” in preparation of the maintenance our Colocation provider will be carrying out https://noc.enta.net/2024/03/planned-work-interxion-datacenter-lon1-crac-unit-replacement/

For the duration of the works the DSL core at this location will be taken down, due to this there will be a loss of resiliency across the DSL estate as all DSL traffic and sessions will be handled via our Telehouse DSL core. Sessions will be drained gracefully from the Interxion LNS pool prior to the works with any remaining sessions forcibly disconnected on the night of the start date before reconnecting to the Telehouse LNS pool.

During the above window our Colocation provider will be carrying out a refresh of the CRAC Units (Aircon) within our suite and the wider datacenter. Units will be replaced one at a time and we do not anticipate service impact to customers.

We apologise for any inconvenience this may cause.
