Problem solved. :)
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.
