In case more data points are required, neither of those servers are
reachable from ISC. We appear to have no route for a.gtld-servers.net
at all, and only a single path for b, which suggests some route
propagation issues (we're well multi-homed in 3557; I'd expect to see
lots of paths).
Maybe Verisign needs more (reliable) v6 transit.

That's not our problem; we see the route to 2001:503:231d::/48 just
fine, for example:
