Hi, I have a very strange routing problem. In the past few days I noticed that I could not reach one my IPv6 enabled servers in the UK. I am currently using the simbx01 POP. To confirm that it is not only my problem, I used your traceroute page and I have noticed that all of the IPv6 POPs that are passing thru 2001:608:0:e01::125 gateway cannot reach neither Slovenian POP or my IPv6 local IP address (same applies for my 6to4 enabled server in the UK). IPv6 POP: 2001:15c0:65ff:88::1 Local IPv6 address: 2001:15c0:65ff:88::2 Traceroute from iedub01, nlams05, fihel01, demuc02, demuc01 (and possibly some others) doesnt work (others do work, but they do not pass 2001:608:0:e01::125 gateway).
