Aggregation switch upgrade programme, per incident 153. Several customers services will be affected during this maintenance window during the switchover.
Up to 15 minutes.
We will be upgrading a number of aggregation switches across UK-1/MA3. The procedure will include powering off the secondary switch, installing the replacement - then briefly suspending traffic flows to redirect over the new switch. Downtime should be kept to an absolute minimum through this process unless an unplanned incident occurs.
