> 10 minutes of ping data, showing awful results

there is unfortuantely no wide-area newsgroup where reports like this
are welcomed; the party line is that you're supposed to contact your
local network service provider to tell them that something's wrong,
and they are supposed to pass the question up and down the line to
pinpoint the problem.  

there was a recent article in ny.nysernet describing some outages in
nysernet which would have affected the nyu to berkeley connection;
here's a quote.

  We are experiencing intermittent connectivity problems in central
  NY this evening as a result of a combination of router and line
  problems.  The resultant routing fluctuations have made access
  to NSS10 (also in central NY) also intermittent at times.  We have
  dispatched technicians and expect the problems to be cleared by 1am
  (6/18/91).  (from levinn@nisc.psi.net)

as a point of order -- there's no good reason that a temporary
"network unreachable" error should cause a perfectly good TCP
connection to be torn down.  unfortunately i can't quote an RFC on
this point but I think it's in 1122/1123.
