At Risk – Network Change 18/2/22 22:00 – 02:00 [completed]

We will make a small network change to update the MTU between a number of our core devices to improve network performance.

This will likely cause a brief blip as the change is applied.

We will update this post as the work completes

[Update 18/2/23]
This work completed just after 10pm yesterday evening and was a sucess


At Risk – Network change 20/2/23 22:00 – 02:00 [completed]

We are planning a window to extend our network to two new Data Centres (Cloud House and Slough

There should be no impact on the services, however this is classed as an “At Risk” maintenance window, due to the nature of the works on core network infrastructure.

We will update this post as the work progresses and completes

[Update 21/2/23]
This wok is completed with no impact


UPS Swap Avro Court [completed]

We have had an alert that the UPS in one of our racks is failing – this is  discrete UPS as a backup in one of our core cabinets and not the main UPS. We will investigate this and swap out as needed.

Most equipment in the rack is dual fed so there will be no impact. However a few devices are single fed so there may be a small number of devices that briefly power down if the UPS needs swapping out

We plan to do this today as while these is short notice we feel it better to work at the weekend rather than a change or possible issue on a week day.

We will update this post as we are on site and investigate

[Update 13/2/23]
This work completed yesterday the faulty UPS was swapped out and replaced. There was a short downtime to a number of services in Huntingdon as one switch that was used to interconnect several racks was fed from the UPS that needed to be swapped

LNS Config Tweak – 19/1/2023 22:00 – 23:30 [completed]

We are making a small change to the config of our new LNS servers for broadband services

This may cause a very brief drop on some PPPoE sessions to us – and your connection may drop. This drop should last more than a few seconds while the router re-connects.

We will update this page as the work progresses


The main config change here has been completed – the only noticeable difference for customers is they may see a different upstream IP on a traceroute in some cases). Some sessions did reset as predicted but we saw all sessions that dropped re-connect. If you do see any issues please reboot your router and if that fails contact support the normal way


Switch Reboot Telehouse North and East [10/10/2022]

Following the advice of Juniper we are deploying an upgrade to the Juniper Software to our core switch in telehouse North and East and rebooting to clear an at risk issue on the switch.

Expected downtime per site is approx 10 minutes – we will update the sites one at a time.

While the switches are working find now we the upgrade clears a known issue that can cause instability which we have seen in the Lab.


At Risk Network Change – 25/09/2022

Through a customer report we have become aware of an issue with a MPLS link across our network. To resolve this we need to change the MTU across some of our core links.

We need to make this change this evening to fully restore service on the link. We will make the change link at a time – Due to the resilience built into our network we don’t anticipate any issue on our network – However with any config change there is a risk of a small number of very brief dropouts or you may see slightly different routing between sites.

We will update this as the work completes
