The supplier of one of our 10G Core links has advised us of a emergency planned works to resolve an issue with a fibre joint in their network overnight between 10pm on the 9th August and 12 midday on 10th August
During this window one of our links between Huntingdon and Manchester will be down. Both sites have resilient links – however with reduced resilience connectivity to these locations should be considered at risk.
We will be closely monitoring our network during this window and will update this post if we see any issues
During the day of 5th July we will have specialist engineers working on our UPS system at our Huntingdon Data Centre.
This should not impact services at all as we have a N+1 redundant system. However there is always a slight risk and we will have slightly lower redundancy during the work
We will update this as the work progresses and completes
During the day of 22nd July we will have specialist engineers working on our Generator system at our Huntingdon Data Centre.
This should not impact services at all as as even in the case of a power failure we have a UPS system. However there is always a slight risk and we will have slightly lower redundancy during the work
We will update this as the work progresses and completes
We have seen one of our core IBR routers crash this afternoon which affected reachability for a subset of customers
Service is now back however we would like to upgrade and reboot the affected devices later this evening to bring them to the latest code and reduce the risk of any further issues.
There are currently four routers left from the upgrade process mentioned in our previous post – we will aim to complete the upgrade and reboot them later this evening and if necessary tomorrow evening – though we hope to complete the work in one evening.
This should have minimal impact to customers as traffic should just route via other core routers but it is obviously ‘at risk’
[update 28/04 9AM]
All work on this completed overnight and we saw very minimal if any impact to customers. All core routers are upgraded and working as expected. If you see any issues related to this please do contact support via the normal routes
We are planning to start a rolling project of upgrading our core routers over the next few weeks – this will involve the LNS routers (those that Broadband customers connect to) and our Internet facing border routers.
In the case of the LNS / Broadband routers this will lead to a brief drop and re-connect of your service when the router is rebooted after the update.
In the case of the core routers this should not be visible as in most cases traffic will simply re-route round them and we will remove traffic from the router we are working on before upgrading it
We will update this posy shortly with a schedule and update on the project
[completed]
All upgrades have been completed for this work.
We have been advised by Virgin Media they will be performing work on a backup link between our Huntingdon and Manchester Data Centre.
The work is scheduled for the early hours of the 19th March.
We do not anticipate any downtime from this but the network does have reduced resilience while this work is being undertake,
