Glad that's out of the way, then.
Yes, IPv6 can make that happen. If the DNS resolver resolves the name
into a IPv6 address, and the kernel believes it can handle the IPv6
while in reality there is no IPv6 path between you and the target, then
TCP/IPv6 will first have to timeout which takes a while. Forcing the
utilisation of IPv4-only addresses makes the problem go away.

Humans will do just fine.
