The ARPAnet reached four nodes on this day in 1969
(anyone know which?)
SRI, UCSD, UCLA, Utah:

All West Coast, plus Utah. Next was BBN; if you look at the IMP numbers, in
HOSTS.TXT, they were assigned in order of installation.
at least one "history" site reckoned the
third node was connected in
1977 ... Well, I can believe that perhaps there were only three left by
then...

1977 was not too many years before the peak in size (with the MILNET split
coming in October, 1983). Per:
http://www.chiappa.net/~jnc/tech/arpanet.html
"Prior to the split, in 1983, there were 113 IMPs in the ARPANET; after the
ARPANET/MILNET split, the MILNET consisted of 65 nodes, leaving the ARPANET
with 68 nodes."
