See "I".  That is the anycasted version of the "J" server.

The data in "J" is the same data in "I".  It's even the same process.

What you do lose is a second path from your machine to the "J" box. 
Think of this in three pieces.  There's your network, the ISP, and my 
network.  If your network goes down, then you lose connectivity 
completely.  If my network goes down I'll switch what you see to 
another node - either another I in IPv4 or to, I think it's K in 
IPv6.  If the ISP fails - that's the issue in play.  You are saying 
you are stuck because the ISP isn't offering v6 - well, yeah, that's 
a problem.  You do have more say in fixing that - you could use a 
tunnel provider or buy transit from someone else.  We can't do much 
more than we are ... no matter who you choose to reach us we will be 
there.  (Providing your ISP is legitimately sending traffic, peering,

The same situation exists with TV and other technologies.  My old TV 
gets only the analog stations on cable and not the digital ones.  My 
car is so old it has the old Freon (CFC-12) in the A/C system, which 
is no longer available.  Both my car and truck came before 
passenger-side airbags, GPS, etc.  And my house is from the 70's and 
lacks sprinkler systems present in newer townhomes.

Technology advances.  You have the choice to retool or lose 
functionality.  Losing functionality isn't necessarily bad - unless 
you consider it critical.

Discussing IPv4 address policy is like deciding what to eat on the Titanic.
