Microsoft’s updated and renamed search engine Bing, formerly Live Search, is now accessible to the public at http://www.bing.com/. Microsoft has also begun to redirect live.com and searches from MSN to Bing. In addition to the more visible changes, which you can find out more about at http://www.discoverbing.com/, Microsoft has made changes behind the scenes. For example, previously the search engine did not handle 301 redirects set to deal with www. vs non-www. URL canonicalization for a website’s home page, while handling it for other pages on the same website. That has now been fixed.
