Perhaps you should try contacting HE support. I hear they're responsive.
I understand however I was pretty sure it wasn't the tunnel that was the problem. So I didn't feel emailing HE was appropriate. I am curious, since I have pretty much confirmed the problem is on my side, why would a move of an IPv6 tunnel from one server to another suddenly cause intermittent outages of a few minutes every couple of hours. It's not as regular so as to suspect a cronjob or something. The old server is still online, however the radvd daemon isn't running there anymore and its external interface has been disabled. There is no IPv6 dhcp server running either. The new server basically has the configuration and IP addresses the old one used to have. It's running radvd. Is there some (obvious) residual effect of having moved an IPv6 tunnel from one physical server to another that I fail to recognise? I have moved ethernet interfaces and cables on the new server to rule out a fault in those. Its internal interface (on the same ethernet card) appears very stable.
