At about 17:40 EDT today we started seeing traffic from planet-lab.orgnodes at 25+ US universities all directed at one of our hosting boxes. Its all ICMP and high port UDP stuff. Nothing terrible from what we can tell, but its triggering a constant stream of IDS alerts and auto-blocks. Not easy to configure for since the traffic originates from subnets all over the place, and the list of originating nodes is growing every few minutes. Its horribly annoying, and trying to determine the source using the tools provided on the planet-lab.org site is pretty much impossible as the search tool returns nothing at all times. Yes, we've opened a ticket with support@planet-lab.org already. Has anyone else had to deal with this, or is anyone connected to that particular project listening? Im all for academic projects, but the approach here is rubbing me the wrong way.
