Users attempting to access search saw an error message from the company.

Yahoo 's search engine went down on Friday afternoon and wasn't restored until the evening. The news followed a Bing search outage earlier on Friday.

"We are aware that Yahoo Search is unavailable to users. Our engineers are working to restore the service at the earliest," a Yahoo spokeswoman told CNBC.

Bing, a Microsoft service, powers Yahoo's search engine. Bing search cut out for about 20 minutes before it was restored, according to reports.

"This morning, some of our customers experienced a brief, isolated services interruption which has now been resolved," a Microsoft spokesman said.
