Dear Customer,

The outage our network experienced Friday 27-08-2010 (http://noc.leaseweb.com/status.php?i=557) was caused by a bug in the IOS-XR software which runs on our Cisco CRS-1 core routers.

More information about the bug can be read on Cisco’s page concerning this issue.

During this maintenance window we will install the update on our CRS-1 router located in EvoSwitch.
The router will be rebooted.
Before the maintenance starts we will reroute all traffic to the core router located in Telecity-2.
Customer traffic loss is not expected.

Kind regards,

LeaseWeb NOC
