BCN NMC added new routes to the WVLS BCN WAN prior to the network being ready for these changes. This caused minor disruption of services. The primary service was DHCP, which would have led to computers losing connectivity incrementally if not addressed soon enough. The issue was caught by the LEAN WI Network Management System (NMS) and Gus Falkenberg raised awareness to WVLS staff immediately. We were able to work with the BCN NMC to rollback the routing adds and resolve connectivity issues.
