This morning I noticed that my Google crawler did not work, Scroogle failed, too. Well, Google has learned something: in HTML it is “<foo bar=”baz”>” and not just “<foo bar=baz>” (smart guys ), they changed their format and added quotes. That will probably increase network-traffic, accelerate global warming and cost millions of dollars, but for some reason they changed it, maybe better compatibility (only 36 validator errors!) – however, it broke Scroogle and my crawler. Scroogle has been fixed, my crawler has been fixed (by the way I have always been using tidy XHTML), everything is working again.
