Unless Cogent is doing something different for Google than HE does for
Cogent, using Cogent is unlikely to solve the timeout issues:
% telnet -6 www.cogentco.com 80
Trying 2001:550:1::cc01...
^C
%
As has already been pointed out, the proper half-baked solution is to
return a destination unreachable packet in these situations, instead
of silently dropping the packets and forcing the clients to go through
a timeout.
