Please note Michiel isn't from XS4ALL :)

We (XS4ALL) did not have any outage on the usenet service, everything  
is still running and passing traffic. The only thing we did was adjust  
some filters so if you are depend on more specifics and not announcing  
the /32 you might have been dropped from the table around 15:00 GMT.

The remaining traffic at ams-ix matches our internal graphs, so I  
guess I'm the only bulk sender at the moment.

There are 3 open usenet servers at amsterdam that I know off:

- XS4ALL (at newszilla6.xs4all.nl)
- Highwinds/Eweka (news.ipv6.eweka.nl)
- XSnews

I think we, once again, have proof 99% of the ams-ix traffic. The  
remaining bit possibly is google and the traffic on this mailinglist  
(and ripe.net).

As an exercise we could see if spikes in nanog activity can be matched  
to spikes in the v6 traffic :)

Groet,
