Not just the global one, as I mentioned earlier it had stopped
responding to link-local pings as well. It seemed like the entire IPv6
stack was dead, to be honest.

In any case, I rebooted it now and now it responds fine to IPv6 pings
again, both to its global and link-local addresses.

Not at home, but I can connect it straight to my ISP's cable modem via a
L2 switch (not behind my HGW as it is today). However my ISP does not
use SLAAC, only DHCPv6 IA_NA - I don't know if the Atlas probes have
gotten support for this nowadays?

Otherwise I could always bring the probe to work and connect it there.
