I was asking how the site knows when its hosts peers have been upgraded, so that it can allow their traffic to be routed out multiple interfaces.
Yeah, exactly, although the canonical Unix-y way to do this would be to try it and see what you get back. If it doesn't work, catch the error and fall back to whatever it is you've planned to fall back to. There are obvious problems with this in a network environment (latency, resource consumption) but it's already how the IETF has chosen to deal with NAT traversal (ICE) so I expect there's a reasonable question about whether or not connectivity tests can (or should) be extended to transport, etc..
