Yahoo Search and Bing Back Online After Outages

Yahoo Search and Bing both suffered outages on Friday. Yahoo's search engine was unavailable for a few hours on Friday afternoon before service was restored in the evening. Bing search cut out for about 20 minutes earlier on Friday before it was restored, according to reports. Bing, a Microsoft service, powers Yahoo's search engine under a 10-year deal announced in 2009. No official word yet on what caused the outages.
