Dear Customer,

Our DWDM platform has redundant path fibers between nodes.
During this maintance we will switchover from the current active path to the backup path between Telecity and Evoswitch. This is due to a planned maintenance on the current active path.

The switchover will complete within 25msec. We have configured our router interfaces to ignore such short link flaps. Some DWDM circuits are connected to carrier routers, those interfaces might flap during the switchover. If these flaps occur there might be a 30 second period of packetloss.

Kind regards,

Leaseweb NOC.
