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 *I took some of the black dots randomly from the map [1] https://atlas.ripe.net/measurements/2009/#!map

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)?
