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.
