Well, a DC600A tape holds about 60Mbytes uncompressed. The daily
traffic started out at about 2MBytes in 15 assorted newsgroups. When
I added comp.sources, it started to fill two tapes. The tape was very
efficient as there were about 4 or 5 Usenet users on the system, some
of which were major corporations. The tape would make the rounds in a
day or two. Those were the days when it was considered amazing if a
UUCP transport email message would arrive in several days, so a 2 day
delay was acceptable.
I eventually gave up and bought a Telebit T2000 modem (19.2Kbits/sec
thruput) and dedicated phone line. I later subscribed to seismo and
later UUNET feeds after ihnp4 died. The bicycle transport system only
worked for about 6 months. However, it wasn't exessive traffic that
killed the bicycle transport system. It was winter and I didn't want
to do it in the rain. I was thinking of writing an RFC for bicycle
transport, but never did.
I had no idea how important Usenet was to my Usenet "customers" until
I got busy one day and couldn't deliver for a few days. It was almost
as if the world was going to end. A temporarily messenger was found
and Usenet deliveries continued. Later, we shared the delivery job.
