Wow, shocked by the image!  I check all G root are IPv4-only, pity.

主题: [dns-operations] g.root-servers.net UDP service

G-root stopped answering over UDP around 0300 UTC
<https://atlas.ripe.net/dnsmon/group/root?dnsmon.session.color_range_pls=0-6
6-66-99-100&dnsmon.session.exclude-errors=true&dnsmon.type=server-probes&dns
mon.server=192.112.36.4&dnsmon.zone=root&dnsmon.startTime=1460575200&dnsmon.
endTime=1460617200&dnsmon.ipVersion=both>
All six instances are affected.

Still works over TCP (and replies to traceroute).

AFAIK, no explanations given. You can imagine your own :-)
