Well, I didn't comment because the thread was drifting a bit already :-)

But anyway.  What we offer is

 - customers can get IPv6 connectivity

 - the backbone and our external links are fully dual-stacked, so we 
   expect and try to provide equal performance within the domain we control

 - we monitor our network for IPv4 and IPv6 breakage (smokeping etc)

 - enough of our staff know about IPv6, so if there is a problem with it,
   it *is* a "supported product" - but not all of the team has had enough
   operational experience with IPv6 yet, so you might be forwared to a
   colleague (who might be busy at the time, and thus things might get
   resolved slower).  So it's not "supported as well as IPv4" yet.

 - if there is a problem "out there in the Internet", chances are that it 
   will take longer to get it fixed with IPv6 than with IPv4 - due to 
   other networks not taking IPv6 serious enough.

 - our SLAs (which is an interesting topic in itself) don't specifically
   mention IPv4 or IPv6, so if a customer's link is broken for IPv6
   due to a problem in our domain ("misconfigured router"), that customer
   could point to the SLAs.  That hasn't happened yet, because usually
   the link is broken due to "copper wires cut", which is fairly protocol
   agnostic :-)

Yes.  Same here, basically.

(We do give customers "Internet access reliability" numbers, based on the
RIPE TTM measurements from the two test boxes in our network, and those
are indeed a bit lower for the IPv6 enabled TTM boxes than for IPv4)
