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
