Happening Monday and Tuesday early mornings:
Most of our LNSs have extra diagnostic and debugging hardware installed which has been used to help us track down the problems we were having with them in early 2024. We are now in a position where we can remove this. We have planned to do this work over two nights: the early hours of February 17th and 18th.
This work will involve us moving customers off the LNSs as we do the work. In practice this means customer connections will experience a drop and reconnect at around 1AM and 4AM on the 17th and 18th February.
BT are performing "Simultaneous Upgrades" which will affect all BT ADSL, VDSL and FTTP services during the early hours of February 12th. It is disappointing that this work is a multi-site activity as we have multiple links to BT in multiple datacentres so as to prevent outages when BT have work to do.
They say:
Start: 2025-02-12 00:01. We're simultaneously upgrading some 21C network software across multiple sites. The PW window is from 00:01 until 07:00, and we will start at 00:01 with non-disruptive pre-checks. From 01:00 we will start to re-boot the devices to the new version of code. This will cause an outage to all customers of up to 15 minutes whilst the device restarts. However, if roll-back is required, the outage could exceed 1hr. All work will be complete by 07:00.
In practice, we expect customers with BT provided connections to drop and reconnect a couple of times in the early hours of February 12th.
