Please note, this maintenance is in the London site, following the successful completion of similar in Slough last night. We apologise that the earlier announcement incorrectly indicated these works were being carried out in Slough on both evenings.

Again, we do not anticipate any impact on services.

We will be undertaking planned maintenance as part of the works to upgrade our BT SS7 interconnects in Slough on the evenings of Wednesday 9th January and Thursday 10th January between 1900 and 0200 each day.

This has been scheduled for when the network is quiet so this will not be service affecting, but this work will result in brief periods of reduced capacity and reduced resilience therefore the service should be considered AT RISK during this time.
