G root pmtu?

2017-04-10 Thread Randy Bush
it seems that G root ops are blocking dns ops mail servers.  the more i
think about that the sicker i think some folk out there are.  but
anyway, anyone else seeing this kind of problem with g root?

http://dnsviz.net/d/gn/dnssec/ whines

gn/DS (alg 8, id 38486): No response was received until the UDP
payload size was decreased, indicating that the server might be
attempting to send a payload that exceeds the path maximum
transmission unit (PMTU) size. (2001:500:12::d0d,
UDP_0_EDNS0_32768_4096)

With a ~59% dual-stack percentage and a 8% ds-lite percentage (aka 67%
of our subscriber base has IPv6), we get around 40% of IPv6 traffic.

My data on customers supposed to be 100% dual-stack (unless they
explicitely disable IPv6 on their side, which some of them do) says 25%
on best days. It used to be up to 35% in late 2015.
For reason unknown, it was going slightly down during 2016, with a
sudden extra decrease in january this year.
