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
Over the next week or so customers may see some additional gateways when connecting with their broadband connections.
We have had these installed and tested in our racks for a few months and are following testing we are happy these are ready for customer use. We don’t suspect any issues for customers – however if anything is seen we will just move the connections back to the original gateways.
The New gateways give us extra capacity and should add additional resilience too.
We will let you know how these go – any customers who have questions or think they may have an issue as a result please contact support via the normal routes
We have been informed that Virgin Media will be performing a re-route on one of the backhaul links between London and our Huntingdon Data Centre between the 24/3/2022 and 25/3/2022
We have resilient links to provide service here however this will reduce the resilience for services in Huntingdon and also reduces resilience to Manchester
The planned work has a 10 hour window however we don’t anticipate the link being down that long.
We will update this post if we see any impact and once the line is restored.
During Monday 14th March our specialist contractors will be replacing the batteries on our UPS in our Huntingdon Data Centre.
While this should have no impact on services – it does pose a slight risk and reduces resilience to services in our Huntingdon Data Centre
We will update as this work progresses
The battery replacement is completed and the UPS and resilience are now back to normal in our Huntingdon Data Centre
During the 15th February 2022 engineers will be replacing the fuel on our generator at our Huntingdon Data Centre.
This will not cause any direct issues and we still have our UPS system to maintain power to the Data Centre. It does however mean that in the event of a power failure on the Utility supply there is a risk as for a short period the Generator will not be available to supply load.
Our suppliers will be working hard to ensue that the at risk period is kept to an absolute minimum
NOTE the new fuel will be the more environmentally friendly HVO fuel as part of our commitment to reduce the environmental impact of our company
We will update this post as the work progresses
This work completed this morning and the generator is back available as needed
