the following is just food for thought. it doesn't provide any conclusive
evidence one way or the other -- in part because I can't provide a
more detailed breakdown on smaller time scales (hourly or less).  all it
provides is single day stats from traffic to/from the states and JANET 
(the UK academic network backbone).

one will notice that there was a larger natural increase in traffic
at the start of the week versus the actual day of 9/11, which seems to
follow Henning's second comment above.
