[NL, AMS-01] Emergency maintenance: Network maintenance on our core network

till

Dear Leaseweb customer,

As part of our commitment to continually improve the level of service Leaseweb provides, we want to inform you about the upcoming emergency maintenance on our network infrastructure.

WHAT CAN I EXPECT?
On the 24th of August 2018, between 05:00 and 07:00 (CEST), we will be performing an emergency network maintenance on our infrastructure in the Netherlands on one of our routers in a redundant setup. During this maintenance your network connection can experience a short interruption when the fail-over will take place from the primary to the secondary router. 

In case you have multiple servers with Leaseweb, this maintenance will only affect those servers whose primary IP address falls within the following ranges:
