Probably not slow and/or overloaded. I'd think it's more likely that it has a routing update problem or an unreliable link. But whatever, this seemed to me to be a classic 'dodgy box in the middle' rather than an end host problem.

Definitly it is somehow unstable. Difficult to find the reason. Anyway Im sure that there is asimmetric routing between me and ipv6.lkml.org and I could see pkts coming back. It might not have been the case for Wichert

Sounds reasonable to me. Could it mean that this router that we are
talking about is simply slow or overloaded ?
