The official distribution goal of Usenet is to have an article transmitted
to 95% of all other sites within 24 hours. Following is a table of the
propagation delay to rlgvax (i.e. Date-Received minus Date-Sent). rlgvax gets
its news hourly from seismo, so there is not much error if we
assume that these numbers also apply to seismo. Since, seismo is a "backbone"
site, we aren't doing as well as we would like.

The longest delays seems to be from Oregon/Washington and Toronto/Waterloo
Both take 5-7 days on the average. The very long delays (over 9) may be a
result of the old articles that have been resubmitted recently.
