Zitat von Ask Bjørn Hansen <[email protected]>:
I need some help debugging it.
The monitoring system should send you a packet every ~15 minutes
from 2607:f238:2::/48
For those of you who have problems, can you run
tcpdump -nn 'net 2607:f238:2::/48'
and let me know what you see? Since traceroutes seem to work fine
both way (?!) it must be something more insidious.

This i got today in my personal inbox:
I'm not on the NTP mailing list myself, so I am mailing you this
information directly. You can pass it along if you like.
A bug was recently discovered in Force10 switches that cause unicast
IPv6 NTP traffic to be erroneously broadcast to all ports. Due to
this, there are currently access lists in place preventing some IPv6
NTP traffic from traversing the DECIX exchange, as it was causing a
storm that generated nearly 1 terabit per second of traffic. This
should be resolved in the near future.

So the culperit is found and as it looks like the problem is also
solved as my server is already at score 19 again.
