I think we just need to recognize that there are Tier 1 providers in other 
countries. Maybe we should replace the term "national" with 
"broad geographic regions encompassing a signficant percentage of a 
continent". Then providers like EUNet would qualify as Tier 1 providers
although, like MCI, they also provide Tier 3 ISP services.

If Sprint, MCI, ANS, Alternet/UUNET, PSI and AGIS/Net99 are the Tier 1 
providers in North America, what networks would qualify as Tier 1in Europe
and the Asia-Pacific region?
