The problem is broken routing tables, and I suspect NSFnet (or its regionals). We have been unable to reach net 128.146 (ohio-state) for a week, and ... By implication, NSFnet is not correctly propagating all of the routes it learns from the ARPANET. (Note that for the most part, we can reach NSFnet sites; only a handful cause trouble.) Case Western is behind the same gateway as Ohio State... The problem is out-of-date software at the gateways in Columbus, Cleveland, and Pittsburgh, from what the local folks managing the net connections have told me, resulting in routing glitches in large quantities and leaving us unable to find lots of places, e.g., I haven't seen utexas.edu in 8 days. The expectation/hope is that the matter will be cleared up within another day or two - an update from The Vendor is on the way. What a mess, --Karl
