Some sites became unreachable ( routing problem ) ![[ru]](/s/countries/ru.gif) Shadow Hawkins on Sunday, 18 March 2012 13:07:51 
Hello.
It seems to be a routing problem since 12:00 at March 16 2012. Some sites became unreachable since this time.
Tunnel is T84298. Pop is ruled01. There are 2 routed subnets over this tunnel: R51398 and R169858.
Here are the output of 'mtr' and 'traceroute' command: 
 user@srv:/root> mtr ipv6.google.com
                             My traceroute  [v0.81]
