I can't reach C, 2001:500:2::c, from many places in v6 land.  My home and
secondary data center can't reach it, but my backup VM's at another data
center can.

Surely IANA has the power to compel a root server operator to abide by policy
or they lose the right to be a root server?

Prior ISP charged me $15/month per IPv4 address and a mandatory router rent of
$10/month.  New one gets $5/month per IPv4 address.  The reason for this is IP
scarcity.  They have plenty of v4 space, so this allows them to charge for it.
v6 isn't going to make them any more money as they can't charge for it.
