Planet-lab.org bringing down my site - dodos attack

[Kate]

I have posted on a couple of other threads re curl requests coming from hundreds of different ip addresses and taking up my resources on gae to the extent that my site is down several hours a day.

I have blocked as many of http://www.planet-lab.org/'s ips that I can but I can only have 100 entries in te blacklist and this isn't enough.

People here have been helpful in identifying subnets but thousands of requests are still getting through.

I have emailed planet-lab but would like to phone them.i suspect it's just a bunch of students making mistakes but there must be some action I can take as I can't keep paying for these curl requests and will have to close down permanently soon.

Any help appreciated. Btw the ips are from within the US, Europe and Asia.
