We accept two servers from ERNET. We finally have 25 servers now. 

I use Stephane's script to generate the priming-response size again:

1) Without DNSSEC

dahu2.yeti.eu.org. 1895 
yeti-ns.wide.ad.jp. 1523
yeti-ns.tisf.net. 1523
yeti-ns.conit.co. 1523
yeti-ns.as59715.net. 1523
yeti-ns3.dns-lab.net. 1523
yeti-ns2.dns-lab.net. 1523
yeti-ns1.dns-lab.net. 1523
yeti-dns01.dnsworkshop.org. 1523
ns-yeti.bondis.org. 1523
dahu1.yeti.eu.org. 1523
ca978112ca1bbdcafac231b39a23dc.yeti-dns.net. 1523
bii.dns-lab.net. 1523
3f79bb7b435b05321651daefd374cd.yeti-dns.net. 1523
3e23e8160039594a33894f6564e1b1.yeti-dns.net. 1523
2e7d2c03a9507ae265ecf5b5356885.yeti-dns.net. 1523
18ac3e7343f016890c510e93f93526.yeti-dns.net. 1523
yeti.aquaray.com. 1215
yeti-ns.switch.ch. 823
yeti-ns.lab.nic.cl. 823
yeti-ns.ix.ru. 823
yeti.ipv6.ernet.in. 823
yeti.bofh.priv.at. 823
xn--r2bi1c.xn--h2bv6c0a.xn--h2brj9c. 823
yeti1.ipv6.ernet.in. (not available now)

Note: dahu2.yeti.eu.org. size is weirdly larger than others. I'm not sure
what's wrong. 

2) With DNSSEC

dahu2.yeti.eu.org. 2053
yeti-ns.tisf.net. 1809
bii.dns-lab.net. 1809
18ac3e7343f016890c510e93f93526.yeti-dns.net. 1809
yeti-ns.wide.ad.jp. 1681
yeti-ns.conit.co. 1681
yeti-ns.as59715.net. 1681
yeti-ns3.dns-lab.net. 1681
yeti-ns2.dns-lab.net. 1681
yeti-ns1.dns-lab.net. 1681
yeti-dns01.dnsworkshop.org. 1681
ns-yeti.bondis.org. 1681
dahu1.yeti.eu.org. 1681
ca978112ca1bbdcafac231b39a23dc.yeti-dns.net. 1681
3f79bb7b435b05321651daefd374cd.yeti-dns.net. 1681
3e23e8160039594a33894f6564e1b1.yeti-dns.net. 1681
2e7d2c03a9507ae265ecf5b5356885.yeti-dns.net. 1681
yeti.aquaray.com. 1205
yeti-ns.lab.nic.cl. 1109
yeti-ns.ix.ru. 1109
yeti-ns.switch.ch. 981
yeti.ipv6.ernet.in. 981
yeti.bofh.priv.at. 981
xn--r2bi1c.xn--h2bv6c0a.xn--h2brj9c. 981
yeti1.ipv6.ernet.in. (not available now)

Note:
dahu2.yeti.eu.org. size is larger than others as it does without DNSSEC
It is observed that the response sizes with DNSSEC are more diverse than
without DNSSEC.

Here are the sizes (in reverse order) of priming responses from Yeti root
name servers:

1) Without DNSSEC

% sh priming-size.sh                                       
yeti-ns3.dns-lab.net. 1400

yeti-ns1.dns-lab.net. 1400
yeti-ns.wide.ad.jp. 1400

yeti-ns.as59715.net. 1204 yeti.ipv6.ernet.in. 756 yeti.bofh.priv.at. 756
yeti-ns.switch.ch. 756 yeti-ns.lab.nic.cl. 756 yeti-ns.ix.ru. 756
yeti-ns.conit.co. 28 dahu2.yeti.eu.org. 

(The last two are problems, to address)

2) With DNSSEC

% sh priming-size.sh
dahu2.yeti.eu.org. 2017
yeti-ns3.dns-lab.net. 1558
yeti-ns2.dns-lab.net. 1558
yeti-ns1.dns-lab.net. 1558

yeti-ns.as59715.net. 1222 yeti.ipv6.ernet.in. 914 yeti.bofh.priv.at. 914
yeti-ns.switch.ch. 914 yeti-ns.lab.nic.cl. 914 yeti-ns.ix.ru. 914
yeti-ns.conit.co. 28

The script was:

#!/bin/sh

NS=$(dig +short +nodnssec +edns +bufsize=4096 NS .) for ns in ${NS}; do
    resp_size=$(dig +dnssec +edns +bufsize=4096 @$ns NS . | grep "MSG SIZE"
|cut -d' ' -f 6)
    echo "$ns $resp_size"
done | sort -n -r -k2
