Scroogle is back. Thanks to the help from three Scroogle users, I learned that there is a way to access that same simple interface with an extra parameter in the URL by using www.google.com/search (that param is &output=ie), instead of through the former static page www.google.com/ie without the extra parameter. It appears that both methods amount to the same thing.
I apologize for the title, "Scroogle has been blocked." It was in an old template, afterwhich the program went on to read a current text file. In the future it will read, "Scroogle is having problems with Google." We were IP blocked by Google more than once a couple years ago, but not all of our servers were blocked at the same time and we rerouted traffic, so no one noticed. We got those blocks lifted by Google within a few days.
