Network Maintenance Windows

[NL, AMS-01, AMS-11] Scheduled emergency maintenance: Network maintenance on our core network [Update]

till

Dear LeaseWeb customer,

[Update 08:55]
Router is back in production. No more changes will be performed unless unforeseen circumstances occur.
We will actively monitor the box for the next hour. 
Maintenance window will close at 10:00 AM CEST(UTC+2).

[Update 08:30]
All checks were cleared and we started to put router back in production. 

[Update 07:45]
Firmware and software upgrades took longer than expected. Maintenance window will be extended. We did not detect any impact so far since 06:30.
Before 06:30 a small number of customer might have experienced latency or packet loss for up to 5 minutes due to a congested link.
Should you experience issues, please let us know by contacting support.

[Update 06:30]
Traffic was shifted completely from the core router and we are progressing with the reboot. 
 
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 4th of June 2018, between 04:00 and 08:00 CEST, we will be performing an emergency network maintenance on our infrastructure in The Netherlands, AMS-01 and AMS-11 locations. During this emergency maintenance the network connection might experience a brief interruption to your services.
 
In case you have multiple servers with LeaseWeb, this emergency maintenance will only affect those servers whose primary IP address falls within the following ranges:
