I have been using queries like these to test:

dig any . @f.root-servers.net | egrep "(DiG 9|AAAA)"
dig +bufsize=1400 any . @f.root-servers.net | egrep "(DiG 9|AAAA)"

The first offers up a standard DNS query, the second an EDNS0 query of
1400 bytes.

In a standard query you're only going to get 3 AAAA records, EDNS0
should allow for all of them.  There are currently 6 servers with AAAA
records:

% dig any . @f.root-servers.net | egrep "(DiG 9|AAAA)"
; <<>> DiG 9.5.0b2 <<>> any . @f.root-servers.net
A.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:503:ba3e::2:30
F.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:500:2f::f
H.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:500:1::803f:235

% dig +bufsize=1400 any . @f.root-servers.net | egrep "(DiG 9|AAAA)"
; <<>> DiG 9.5.0b2 <<>> +bufsize=1400 any . @f.root-servers.net
A.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:503:ba3e::2:30
F.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:500:2f::f
H.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:500:1::803f:235
J.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:503:c27::2:30
K.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:7fd::1
M.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:dc3::35

It is also the case that various servers are still getting up to
date; virtually all the root servers are more than one machine
either load balanced or anycasted.  As a result YMMV until everything
is in sync again.

Rest assured, those who run root servers are paying very close
attention today.

I've already helped people fix two problems, both a result of ISP's
filtering the RIR's micro-allocation blocks in ways they should not be
doing.  Please, if you have IPv6 filters make sure you've updated them
to allow down to a /48 in the various RIR's micro allocation blocks
(recently posted to nanog by someone else).
