If one DNS server for a ccTLD goes down, there are lots of secondaries
that queries can go to.  A normal end user won't even notice.

If the primary goes down and needs to change IPs, that's primarily a 
non-user-visible change in the configuration of the secondary name
servers.

Distribute your secondary name servers well, and a single nameserver
going down won't do that much hurt.  Of course procedures should be
into place to change the glue records quickly (in the range of "hours",
instead of "months").

In which way are ccTLDs related to public exchange points?  Or are you
referring to the discussed "abandon PI" policy change?
