This building houses the NSFNET routers (NSS 17 and ENSS 131) in Ann Arbor. This should have the following effects: NSS 17 will be down for 10 minutes at 23:30 on 4/20/91 and for 10 minutes at 07:00 4/21/91. ENSS 131 will be down from 23:30 on 4/20/91 until 07:00 4/21/91. All Ann Arbor Regionals (MichNet, UMNet and CNRI) will be unreachable from 23:30 on 4/20/91 until 07:00 4/21/91. It is likely the work will be completed in less time than the window allows for, in which case the Ann Arbor Regionals will become reachable and ENSS 131 will come back into service. --Steve Widmayer Merit Network Operations
