XMission will be replacing one of our border routers tonight, during a maintenance window between midnight and 6 AM. We will be decommissioning one of our Juniper MX240 routers and replacing it with a Juniper MX204, which will be able to scale with our bandwidth needs as we upgrade our network to handle 100 Gbps speeds. This maintenance is not expected to impact service to our customers, but a handful of users who peer with this router can expect downtime of between 15-60 minutes as we bring the new router online.
