It works from here:

$ dig -6 @2001:500:12::d0d +short
l.root-servers.net.
i.root-servers.net.
c.root-servers.net.
g.root-servers.net.
d.root-servers.net.
k.root-servers.net.
b.root-servers.net.
e.root-servers.net.
f.root-servers.net.
a.root-servers.net.
j.root-servers.net.
m.root-servers.net.
h.root-servers.net.

Note that the RIPE NCC has a running measurement against all kinds of 
"important" DNS servers called DNSMON, which includes the root servers:

https://atlas.ripe.net/dnsmon/group/g-root

You can check that at any time.
