Subject RE: [users@httpd] Narrowing Down A Strange Problem
Date Wed, 15 Sep 2004 15:55:30 GMT
So far people who can view the site are in:
  South Carolina
  North Carolina
  Missouri
  Arkansas
And people who can not are int:
  Massachusetts
  New York
  California

The only pattern I can derive from that data is the number of hops in
the route.
