Currently, Mark is running one Broker instance and Webinterface at the University of Aachen.
Broker: 220.127.116.11 port 10001
This setup is suspect to change and will probably be down once in a while. In the last few weeks it has been running without downtime, though.
We are working on an instance in the Honeycloud provided by Sjur. This will most likely be the main HPFeed setup for any Honeynet Project related channels.
Details / Connection info will be made available here.
