As part of our plan to enhance our network capacity and resilience over the next few days we will be migrating a number of core links to a new model of EPVN. The new config will be in place before any old links are removed. However there is a risk through this for brief drops and routing changes being visible.
This has already been tested in our lab and the configuraton is in place the final changes are just to move from the old configuration to the new setup
We apologise for the short notice for this work
We will update as the work progresses
[Update 1]
The work on the IBR core routers completed yesterday bringing our new Manchester core routers all live. There is some work this evening on our Juniper Core routers – again we don’t expect any substantal issues but you may notice some routing changes and bried periods of packet loss as the new routing converges

Our Supplier Engineers will be performing their regular service on our Generator system at our Huntingdon Data Centre during the day of 15/7/22
This should have no impact on services but we treat this ‘at risk’ in case of any unexpected issues. The only possible impact here is that the auto changeover in case of a power failure will not function – However our UPS will be available and will cover the power until the Generator can be manually started
We will update this as the work completes

Our Supplier Engineers will be performing their regular service on our UPS system at our Huntingdon Data Centre during the day of 14/7/22
This should have no impact on services but we treat this ‘at risk’ in case of any unexpected issues. NOTE that we have three resilient UPS modules and only one will be worked on at a time
We will update this as the work completes

Following the recent issue on our core switch issue – our switch vendor has asked us to urgently upgrade the firmware version on our Juniper switches to a new release they have provided us to clear a bug located through their investigations.
Due to the potential of a repeat of the previous issue we are performing the upgrade this evening to ensure there is no impact on service this coming week and to ensure the service is stable and with full resilience for the week.
In normal circumstances this would be performed out of hours / however to ensure that we have the resources available should any unexpected issues occur we are performing these upgrades through this evening meaning that IF we need to reboot / upgrade the core routers we can perform this later
The customer affect of this work will be a short period of packet loss when the affected switch reloads with the latest version of the firmware – there may be a small number of sorter periods of packet loss when other (not directly connected) switches reboot.
We anticipate the switch work will complete in the next 20 minutes
Again we apologise for the short notice on this change

We are planning to replace our Juniper EX Series core switches in Telehouse with a newer more powerful model to allow for network growth and increased stability.
We are currently planning on working on the first two sites in Telehouse on Thursday 7th April – we will be working on one site at a time. During the work services will be at risk and access to directly connected connected servers and routers will be affected. Switches will be pre-configured and we hope that the outage per site will not exceed 2 hours. Once we are happy that all woek on one site is complete and the network is stable we will then work on the second site.
In many cases services connected will move to an alternative site – However with some connections including OFNL lines, these will be down for thr duration of the work.
We will update post before and during the work

We have seen a few brief drop outs during today for a small number of customers due to a switch in Telehouse West having forwarding issues on a number of core VLANs passing thought that Data Centre.
We’d been planning to announce a switch reboot late this evening to resolve this – however the drops have become more regular this afternoon and we have taken the decision to reboot the switch this afternoon to clear the issue.
We are aware of the cause of the issue (a bug in Juniper OS that sometimes strikes after a config update and had plans to upgrade the switches to more powerful model last week – However as one of our engineers has COVID this work has been slightly delayed.
We can see the switch is now back up and passing traffic – sorry for the lack of notice here but we wanted to restore the stability as quickly as we could and ensure that all services work as they should
