From sunday 26-1 23:00 until monday 04:00 we will be replacing/upgrading one of our core routers with a newer model. Although our network is setup with redundancy, some downtime may occur. Directly affected customers have been informed. For customers who are not directly affected: our other core routers should take over it's tasks, all traffic should be failover to our other locations. Incidental outage may occur until completion of the maintenance.
