As part of on-going improvements in BTs core network, BT need to make some changes at multiple sites. The work will start at 00:01 with an expected service outage of about 60 minutes beginning at 02:00. BT plan to be finished by 03:00 , however if BT encounter additional problems, service outage could extend to 06:00
We expect this to affect most of our customers on BT backhaul.
