[atlas] ipv6 ping to root name servers failing?

Hi,

it is not only for your probe / connection / ISP. See the result map of the measurement [1].

In Germany the probes from AS3320 (DTAG / Deutsche Telekom) and AS31334 (Kabel Deutschland / Vodafone) are not able to reach the destination*.

Maybe same uplink provider?

Greetings,
Christian
