A part of a change to BT's UK core network they are performing work that will, unfortunately, impact all our BT DSL services (ADSL, FTTC G.FAST, FTTP) in the early hours of 18th August as follows:
BT are upgrading some 21C network software in Multiple Sites. The outage to all customers will be approx 15 minutes whilst the device is rebooted. This could extend to 1 hour if roll back is required to reboot to the old code. The downtime will start some time after 01:00 We plan to be finished by 04:00 , however if we encounter additional problems, service outage could extend to 06:00
For resilience, we have separate links to BT which are provided in different datacentres and which lead back to different BT exchanges. This should mean than we can carry on working during BT planned works or core network outages, however this is not the case this time. We are disappointed that this work is seemingly needed to be done to all our links to BT at the same time.
Customers with services via TalkTalk will be unaffected by this.
BT have completed their work. Unexpectedly, It it not affect any of our services. All our links to BT remained operating as normal during their work.
