If you (or your customers) have difficulties resolving domains
in the US zone, it was moved recently moved to a new set of
servers. Nothing special, except they are all in 209 net
space, and are being announced as /24 network routes. There
is no covering CIDR aggregate being announced, so providers
which still filter 209 CIDR blocks (i.e. an obsolete copy of
access-list 112) you may have difficulty reaching the new
servers.

This is strictly a network routing issue, and has nothing to
do the merits of Neustar, ICANN or any other DNS issue. If
you, and all your upstreams, accept /24's you shouldn't see
any problems.
