In an attempt to stabilize the networks in Iowa and to restore full connectivity to all IP subnets, the Network Services Team will perform some emergency intrusive hardware testing of one of the devices on 23-MAR-2010 at 00:00. During this time, we expect customer connectivity to experience brief periods of unavailability as the testing progresses, with a total disruption of 20 minutes or less. We appreciate your patience while we complete this emergency work tonight.
