Hi!
I see v6 connectivity is much worse than v4:

And some parts of v6 Internet is completly unreachable. Is it my bug or real situation?
According to your test, and my quick test, it seems to me that there is some IPv6 connectivity problem inside Surfnet. Regards, Janos Mohacsi Network Engineer, Research Associate, Head of Network Planning NIIF/HUNGARNET, HUNGARY Key 00F9AF98: 8645 1312 D249 471B DBAE 21A2 9F52 0D1F 00F9 AF98
