I've recently changed my IPv4 endpoint (on 27.08.2009) on my tunnel T14597. Since then, according to graphs on the "Tunnel information" page, packet losses for my IPv6 address (2001:6a0:200:6d::2) are high. Also, I received an e-mail about my tunnel downtime (and get -5 penalty ISK). The problem is that this tunnel was up for the whole time (and still is). I can ping PoP IPv6 (2001:6a0:200:6d::1) and other IPv6 addresses, like e.g. ipv6.google.com. I've also tried using your online traceroute tool on my IPv6 address - it also works without a problem. What can I do about it?
