Traffic statistics concerning my tunnel (number 40405 with endpoint 130.149.221.219) are interrupted since early afternoon 30.11.2011. The tunnel is working, ping latency and loss% show correct statistics. Nothing has changed in my setup for several months, hence suggesting the problem is on your side. Can you please check on your side. Note that connectivity is working correctly it is just the graphs, hence you can give low priority to this ticket. Thanks.

I check with tcpdump traffic flow without problem, hence connectivity is not affected. the pop status of decng01 is currently UP.
