There are some websites particularly 2 examples niu.edu & glos.ac.uk as examples both explicitly use www. infront of there names only e.g http://www.glos.ac.uk will work but http://glos.ac.uk does not. this means that it would not page resolve to there webpages.
Update: this spans more then the educational community (but all 95+ UK unis use 'explicit www' [as i call it]) so adding Cardiff Uni, Oxford Uni etc will get same result

When you block glos.ac.uk all subdomains will be blocked, so that includes webmail.glos.ac.uk and www.glos.ac.uk

What if "example.com" and "www.example.com" were both websites *and* they each had different content? A bit of a pathological case, yes, but if it were to happen, could these be tagged distinctly as things stand today?
Even assuming that www.example.tld and example.tld have the same A record, and even use the same document root on the webserver, the content could vary. On apache for instance, one could easily configure their .htaccess in such a manner that example.tld. goes to a nice clean educational website, and would generate a 404 if users tried to access /other/really-bad-stuff which lets say hypothetically contains p0rn. Users who go to www.example.tld. could be redirected to, and allowed to access, /other/really-bad-stuff
This would kindof hamper filtering efforts if we wrongly assume that the www makes no difference, even if the A record is the same!

This is a urgent problem i found as some sites whould bring errors up even if it is a ligit site and this spans more then the educational community i done noticed it on serveral occasions before the new categories were set up
