Just a couple of points on that code.

1. I think you meant keys %sites
2. I find the object interface to CGI.pm clutters code up unnecessarily and can confuse beginners

Here's a complete test program based on your code:

#!/usr/bin/perl  -w

use strict;
use CGI qw (:standard);

my %sites;

while (<DATA>) {
  chomp;
  my($name, @status) = split/\|/;
  $sites{$name} = [@status];
}

print header;
print start_html;

print table(Tr(th(['Site Name', 'Site Address', 
                   'Status', 'Comments'])),
            Tr([ map { td([$_, @{$sites{$_}}])} keys %sites ]));

print end_html;
