    Past Maintenance
    Chicago Border Router Connectivity Migration

    Cedar Falls Utilities will be migrating the connectivity for our Chicago border router to a new core router. This will involve draining the transit and peering traffic from the Chicago border router prior to the migration. This will divert that traffic to our other transit and peering interconnections for all CFU Internet customers. We don't anticipate any disruption of traffic during this maintenance.
