Silicon Valley reported that Microsoft’s MSN search engine stopped working for about four hours Thursday. Microsoft spokesman Justin Osmer said in an e-mail that the company was still trying to determine what went wrong.
During the outage, which began about 8:30 am and was being restored as of about 12:15 pm, users who tried to find Web pages were told the service was unavailable.
Microsoft’s MSN Search is the No. 3 search provider in the United States, according to Nielsen/NetRatings, behind market leaders Google Inc. and Yahoo Inc. Nielsen/NetRatings said MSN provided 10.7 percent of all U.S. search results in February, compared with 48.5 percent for Google and 22.5 percent for Yahoo.
