Can't reach RIPE WHOIS via IPv6 ?

(I realize RIPE is not in North America, but we get a lot of traffic
from their IP space.)

When I try to contact whois.ripe.net (2001:67c:2e8:22::c100:687) or
their REST server rest.db.ripe.net (2001:67c:2e8:22::c100:68e), it
times out.  Traceroutes from a couple of different places all seem to
loop in Amsterdam, IPv4 is fine.

Am I special, or is it just broken?

R's,
