All The Best!!! I am not a Nutch Developer... I think I found a bug in Nutch's "Robot" implementation... Also, today I found a bug in their HTTP implmentation... But I don't have any time to re-test, and, probably, to add some code! Good luck, Fuad

Although it appears from our research there was a Canadian contingency that assisted in the development of an earlier version of the Nutch Crawler at UW. Regardless, this has nothing to do with the Canadian's IP. The very first post indicated the offending IP is in fact owned by the University of Washington, as is referenced above. Who, by the way has completely denied the error in their ways and is in fact alluding to the fact the only reason Their crawler spent so much time at Our server was due to OUR server configuration. Completely LAME UW, not the way to handle this issue. The Ducks are trying to DUCK the issues here. We suppose, because they feel they are a University, with virtually unlimited bandwidth, they are allowed to swamp people's servers with anything they want and anytime they desire. We are disgusted an academic institution, a place of higher learning, the source of education and ethics for young impressionable minds, would attempt to pass-the-buck like this. Especially UW. The facts are as follows... 1) 202 sessions on our main server since the 18th of this month. 2) 328 minutes and 08 seconds of crawl time from 128.95.1.189 turingc.cs.washington.edu since the 18th of this month. 3) Indeed this crawler is ignoring our robots.txt file, go have a look at our file for yourself. It was installed the same day we noticed your abusive crawler hitting our site with 30X the bandwidth and regularity of all the Google bots combined. Despite the robots.txt file being in place, your crawler continued to scan our server with obvious and continuing disregard for the implemented robots.txt file. This is the Internet, and while people are free to do as they please without harming others, this is NOT UW's friggin' playground. And someone at UW should step-up and say, Sorry, instead trying to pass-the-buck like some two-year old. We expect nothing less than an apology from UW.
