I just noticed - informed by e-mail - that all my 3 server with IPv6 are dropped out from the pool. Looking at the CSV protocol there are periods of not reachable. But this issue exists only for IPv6. IPv4 server has a score of 20. Of course I am monitoring my NTP server as well as the Internet line with different tools. But I can’t see any issues. Either for NTP server nor for the line.
Are there any IPv6 hiccups in Internet between LA and Vienna ?
Did someone else see similar issues around my area ?
