Both probes lost all internet connectivity for a couple of hours. I have no idea what happened but Atlas traceroutes stop at hop 1 (and don't even reach the local router).
Yes, but the problem was not with the networking infrastructure: For me the most obvious approach is to put the probes behind a switch

The fact that it happens to both probes at the same time makes it very unlikely that it is a probe specific hardware problem. I'm not aware of any bugs in the Linux kernel that would affect IPv4 and IPv6 at the same time. So the obvious next step is to check what actually goes over the wire.
