During the day, not during the few days. At Bellcore, we shut down
most of our network the morning of the attack, and were back up
(mostly) the same evening.

Also, Usenet was *not* carried primarily over the internet at that
time -- it still went (mostly) over dialup modems.

Untrue.

0) Most sites did not have BITNET. We didn't have BITNET at
Bellcore, for example.
1) eradicating the worm on any given host was very easy. The problem
was, of course, that it tended to go runaway, driving up the load, but
once you got that under control, it was easy to delete the thing. The
real problem was you tended to get re-infected immediately if you
didn't segment your network and sterilize all the machines on any
given subsegment before reconnecting them together.
2) most of the work being done coordinating decompilation of the worm
went on over the phone. I remember chatting extensively with some
folks at Berkeley and elsewhere who were decompiling the thing. Once
we knew that it contained nothing malicious, most of us just turned
everything back on again.

The worm, as deployed, attacked Suns (68k processors, at that time)
and Vaxen. Other machines were not, of course, impacted.
