Yes, currently less than 0.05% of end users and usually because they have misconfigured systems that think they have 
IPv6 access when they really don't.

One could make a valid argument that this is no worse than systems with misconfigured IPv4 who cannot reach Google at 
all even if they don't publish AAAA records because their IPv4 is so badly misconfigured that it doesn't work either. I 
suspect it may well be approximately the same fraction of systems, though it may take longer to notice/resolve the IPv6 
issues than the IPv4 ones.
