It seems that your IPv6 connection has issues. Around the time the ssh connection fails, I also see IPv6 traceroutes with problems. But it is relatively far from the probe, so it is hard to be sure about the source of the problem. One option would be run a traceroute on your probe with relatively high frequency (once a minute) to see if you can spot any pattern in the traceroute output. Philip
