There is a fiber cut affecting several links to both Nottingham and Sheffield pops, all services are running over alternate paths. Customers connected via the Sheffield pop may notice a small increase in latency due to the increased path length.
Our carriers engineers are currently working to determine the exact fault location.
We currently do not have an ETR, further updates will follow.
-
OTDR test results from the Sheffield end indicate a fault 30 km from Sheffield.
No ETR yet.

All links were fully operational by 01:30, affected sites are no longer at risk.

Posted: Tuesday, June 2nd, 2009 at 17:04 by Steve Lalonde

We have just been informed by our carrier that there will be work taking place between Sheffield and Leeds at the above times. Urgent outage required to remove excessive loss which is resulting in hits/errors on a Sheffield to Leeds DWDM system.
No outage is expected as traffic will route to these sites over alternative paths, both sites should be considered at risk during the maintenance window.

All links were back in service by 02:30, traffic during the maintenance routed over the configured alternative paths.
This maintenance window is now closed.
Service was restored at 23:24, all traffic is now back on the optimal path and both sites are no longer considered at risk.
