We might have a general problem with IPv6... We (AS34288) have native IPv6 connectivity, we're peering at several exchanges and have about 500 direct and native IPv6 peerings. Nevertheless the IPv6 monitoring sees constant problems with packet loss. I cannot see any problem on my side. I

I have a server in the UK which has both IPv4 and IPv6. There's not packet loss on IPv4 but there is with the IPv6 one. This is the same instance of NTPd so it's extremely unlikely it has anything to do with the server itself. - Svavar On 16/06/12 19:01, Maurice Janssen wrote: Hi, I have
