I'm not on cox, but i do daily svn's from host svnmir.nyi.freebsd.org. (2610:1c1:1:606c::e6a:0) to my colo in NJ. I've seen no problems (indeed, a just did a manual checkout and confirmed it was on ip6) The thing is, you don't say which of the geo-servers you are connecting to.. I'd humbly suggest creating a temporary ip6-4 tunnel from https://tunnelbroker.net/ - they have POPs in Miami and New York, amongst other places. That would at least help you test the non-cox ip6 side of things, especially if you can get a 6-4 server close to you. cheers, jamie
