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
