For my ipv6 capable probe it has been the j-root not answering v6 pings 
since the beginning of October 2017. The a-root my probe ends at was 
also not replying to v6 pings from October 2017 to December 2017 and 
intermittently since then. Both roots are operated by Verisign, maybe 
they have configs at some of their anycast sites that drop v6 ping. They 
do answer dns queries for me when I've tried it from a machine in the 
same network as the probe.

I have also noticed the ipv6 stable tags coming and going, maybe this 
has something to do with it.
