CONCERT is alive and using/depending on the T3 network. Our ENSS to CNSS
link to the T3 backbone is T1. Traceroutes from here indicate paths to both
VPI and Purdue are via the T3 infrastructure. I believe we experienced
about all known problems with the T3 network during late Summer and early
Fall. None of those problems have reappeared since about mid November.
The T3 network is running very well. The difficulties with the T3 network
were no different that what I remember with the start-up of the T1 network
and rather less painful than the old fuzzball original NSFNET. Before
that we had one of the last preferred 1822J ARPANET links (better than the
IP over X.25 links DARPA used towards the end). Then I recall week after week
having to call ARPANET NOC folks with repeated link/performance problems.
When there were not ARPANET problems, then we were struggling with keeping
the gateway Vax 11/750 running (and twidling gated configs). We've really
come a long way since the mid 80s.
