Network changes 3/6/2014

One of our transit Providers will be making a small change to their connection in the early hours of 3rd June. We have multiple Transit providers so this *should* have no impact on our service as traffic will be moved gracefully away from this provider before the work happens and then switched back as soon as the work is complete.

We will update this post as the work completes

This work is completed

UPS Manintanance – Huntingdon [29/05/2014] Completed

Our UPS at the Huntingdon  Data Centre will be having it’s planned maintenance on 29/05/2014. This is to test and ensure it is performing as it should.

This should have no impact on customers BUT it will involve some test periods on UPS loads and there may be some short periods where the building is running on raw mains rather than on the UPS feed.

With any work on on near the UPS there is a small risk of a problem to services in Huntingdon – However this is very very low.

This work is completed. Unfortunately the engineer tripped one phase of the power during the work. All power is back – we are just checking all servers have returned to service

Network Change 28/05/2014 [completed]

We will be making two very small network changes today. Neither *should* cause any issues BUT may cause some very short blips

1) We are moving the switch that one of our London to Manchester links is connected to. There are redundant paths BUT you may see a blip for ~1 minute while this link moves as traffic moves to alternative paths

2) Later this evening we will be re-enabling a redundant link in London. This should not have any impact BUT again there is a small risk of a blip as the network re-converges. IF we see any issues we will simply disable the link.

The first change (as it is low risk) will be performed by engineers at the data centre some point today. The second change will happen this evening.

This work is completed – all resilient links are now working in London and you should see a improvement on service and speed from this work. We *may* be some network balancing across the links but we will review this and announce this at a later date

Planned Work HEX – 13/05/2014 [Completed]

We will be performing some planned works in our Harbour Exchange Data Centre during the evening of Tuesday 13th May.

The work will involve replacing one of our core routers with two new routers and the upgrade on one of the switches in the Rack.

We have already moved traffic away from the router in question so the router change should have no impact. As the switch is replaced there may be some brief interruptions to some services in Avro Court as one of the links is via the switch being upgraded. We hope that any outage will be a matter of minutes as cables are patched to the new switch.

We plan to bring the new router into service overnight if possible – if not this will happen at some point on Wednesday

This work was completed in the early hours of 14/05
