Re: [ga] DNS Root-Level Pollution

[David Scott <tlda@xxxxxxxxxx>]

With this upcoming fiasco, (the auction of TLD's) does this mean the 
internet will go away? oh pooh :(
Hopefully there is enough RSC's out there that can take the load. The 
structure of most of the worlds economics actually rely on the internet 
in one way or another; and incidentally ICANN's structure. (have to use 
them to get the dot coms)
If ICANN's structure where to completely fail, I mean 100% failure, what 
is the real impact. I don't think really anyone could understand that, 
and on top of which, since they are not allowing completely AXFR's from 
their servers, (that i know, haven't check it lately) when.. i mean IF 
they fall, how long before the caches actually clear?
Was 7 really enough. Guess closing doors MIGHT have been a bad idea huh?
