Time: November 23, 2015 15:04:00 (CET)
Dear Leaseweb Customer,

[Final UPDATE 17:25]
Our engineers have investigated the issue further and can confirm everything is stable again.
The outage was caused due to an unexpected routing protocol drop on the router, which caused traffic to be dropped for a short while.
For the next 48 hours will we closely monitor the behaviour of the router to guarantee the stability and reliability of the network.

[UPDATE 15:20]
Currently connectivity has been restored and traffic is back to normal levels. Our engineers are working to identify the root cause of this issue.

[UPDATE 14:50]

[NL, AMS-01] Connectivity issues in part of our Network [Update]

Time: November 19, 2015 16:22:00 (CET)
Dear Leaseweb Customer,

At the moment we are experiencing connectivity issues in part of our Network. We are currently working on the issue. Updates will follow via this NOC posting.

[UPDATE 17:15]
We have found the issue, one of the core routers was black-holing traffic. We restored traffic levels to normal and we are investigating further.

If you still experience issues, please don't hesitate to contact us.

[UPDATE 20th Nov 11:30]
After investigating further, we found that a change we made on one of the core routers triggered the traffic to switch from the PNI sessions to carrier links. The amount of traffic that was switched caused a few links to be congested, so customers could have experienced latency and packet loss.
We are in the process of implementing egress prefix filters to avoid incidents like this.
