We are aware of an issue with one of our Juniper Core Routers in Harbour Exchange Square.

The vast majority of services have routed round this and are not affected. As small number of directly connected customer may be seeing an issue

Our Engineers are working to restore service to this router. We will update this as we know more

[Update 18:40]
A remote hands reboot of the core router has not restored service. Our Engineers are therefore en-route to the data centre to investigate and restore service – we expect them to be on site by approx 20:15 this evening. We will update as soon as they arrive.

[Update 20:15]
Our Engineer is approx 20 minutes from the Data Centre they have collected spare parts on route in case any hardware needs swapping out. Next update by 21:15

[Update 21:15]
Our engineer is on site and working on the core router. We can see the file system is corrupt which means the router did not boot when power cycled. We are working to restore this asap. In parallel we have moved some lines onto the switch on site which is working. We are moving other links as well to restore their service. Next update within an hour

[Update 22:45]
The Router is now booted after the disk corruption was cleared. Config is being copied back & applied. We hope to have service restored very shortly. Next update by 23:30

[Update 23:20]
The router is now back and passing traffic – we have not yet enabled all peers so some traffic may take a slightly different route to ‘normal’ but no customer services are now impacted. As part of the recovery the software upgrade planned for this router has been applied so the planned work for that upgrade is no longer needed

[Update 23:30]
During the checking process we have detected the need for a reboot to ensure the router and config are updated completely. The reboot is in progress and we will expect this to complete in 10-20 minutes

[Update 23:50]
The reboot cleared the router alarm and all routing is now back up. Monitoring is now showing all links working as they should be. There will be some further checks to complete – however we do not expect any further issues. We apologise for any customers affected by the issues this evening.
