No way! You could take those 15,000 and multiply by three and still come up
short. Nearly every map entry I'm aware of (for Alberta anyway) hides
*at* *least* three additional machines behind it. We publish one map
entry that represents about 25 systems. The U of Alberta is similar.
With the conversion to domain names, many sites just list their gateway
system(s) in the maps. Therefore it's safe to say that the number of
UUCP machines is much larger than the number you gave, although there
is no practical way to determine the number of machines on each of
these "networks."

These days it seems that the number of non-822 conformant sites
matches closely the number of connected sites running AT&T System V :-)
