As of April 4, 1994, the NSFNET Backbone Service to Argonne and CICnet at Argonne, IL (ENSS 130) has been retired. The termination of service means that Argonne (683) is totally dependent on its new service provider. CICnet (AS 1225) continues to have connectivity via the NSFNET Backbone Service at Ann Arbor, Michigan and Champaign, IL. We thank Argonne and CICnet for volunteering to terminate the NSFNET service at Argonne. --Elise
