[atlas] ipv6 ping to root name servers failing?

[Tapio Sokura]

Hello,

I noticed a few days ago from the built-in probe graphs that ipv6 pings 
started to fail to the a-root name server instance serving the probe I 
host. Now also the j-root serving the probe is dropping pings. Some 
other instances of the same root servers at the moment are still 
answering pings.

If it is intentional that root name servers are starting to drop pings, 
something should probably be done to the built-in probe 
measurements/graphs. Does someone know more about this, will all roots 
be dropping pings in the future or is this just a Verisign thing (a and 
j operator)?
