Turnning off the servers will not reduce the brokenness of 6to4, it will =
increase it.
The best way to get rid of 6to4 is to deploy native IPv6.
The best way to improve 6to4 behavior until that time is to deploy more, =
not less 6to4 relays.
Hurricane Electric has proven this.
Comcast has proven this.
Every provider that has deployed more 6to4 relays has proven this.

The best way to make 6to4 diminish has always been and still remains:
Deploy Native IPv6 Now.
That's a plan and a necessity at this point, but, execution is still =
somewhat lagging.
