That is because you left out half of the sentence:

  since M$ NT sends packets with DF on by default, [and]
  many clueless firewall administrators block all ICMP,
  and a lot of layer4 load balancing switches are broken wrt sending
	ICMP_FRAG_NEEDED back to the source (like www.google.com!)
  ===>
  nobody will notice one site more being severly broken.

It might not be the greatest sentence I ever constructed though which
isn't surprising if you look at what time I posted it :)

I recently set up a tunnel with an MTU of 1472 to link a site to the
Internet, and most NT based sites (www.telefoongids.kpn-telecom.nl
for example) and even www.google.com simply didn't work.
