A few days back, I noticed that all my Bing keyword results started showing "No results available". After poking around in the script a bit and dumping the results, it looks like the xml returned from Bing by curl indeed does not contain any results. If I request the same URL in my browser, it works fine. An example URL: http://www.bing.com/search?format=rss&first=1&q=my+query Visit that in your browser and you'll see results. If the tracker script requests it instead, there are no results. Are they blocking curl? Blocking by IP? Anyone else having issues?
