Or you haven't noticed it :-)

We have been doing native IPv6 in that 200-odd devices network for about 
six years. I have only very recently seen the first of those issues, and 
I have no idea at all how frequent they are. At least in our case, it 
fails completely graceful and just switches over to ISATAP or IPv4-only. 
So far I have only seen two users complaining, one who had disabled 
ISATAP and could not access IPv6-only resources anymore (we have very 
few of those), and one who switched to ISATAP and was blocked by his own 
over-eager ACL on a host.

Other than that, I had always wondered about the tiny fraction of ISATAP 
from networks with native IPv6, but I had never bothered. I'm going to 
have a closer look.
