We are scheduling two maintenance windows to upgrade the version of IOS-XR on our core routers in BT Citywest. These maintenance windows will impact a number of services for the duration.
Customers may experience brief periods of packet loss and increased latency as the network re-converges. Services in BT Citywest should be considered at risk during these maintenance windows.
