[atlas] IPv6 auto-tagging failure?

Dear Bjørn,

This was caused by an issue with the particular controller that your
probe was connected to. This issue affected 30 probes in total, and
prevented their IPv6 capability from being properly detected.

The problem has now been fixed, and you can see that your probe is now
tagged as "IPv6 Capable". Within a few hours it will also be tagged as
"IPv6 Works" as long as it carries out successful IPv6 measurement results.

Sorry for the inconvenience, and thanks for pointing this out!

Regards,
