Microsoft And Yahoo Confirm Search Outages

Microsoft’s search engine and other sites, including, suffered a brief outage of somewhere around 20 minutes today, give or take, according to reports on Twitter and other website-monitoring services. While and others have since returned (in fact, while we were reaching out for comment on the outage), we noticed also that Yahoo’s search service (powered by Bing) at is currently down, as well. We’re reaching out to see if there’s any explanation being provided for the outages.

We’ve reached out to both companies for a further explanation or official response, but comms and PR staff are still working a holiday schedule which means answers could be delayed.

Update,1/2/15, 3:30 PM ET: Microsoft has confirmed the outage with a brief statement:

“This morning Microsoft experienced a brief, isolated services outage which has now been resolved. Our apologies for any inconvenience.”

Update 2, 1/2/15, 4:20 PM ET: Yahoo has also confirmed its outage:

“We are aware that Yahoo Search is unavailable to users. Our engineers are working to restore the service at the earliest.”

Update 3, 1/2/15, 8:10 PM ET: Yahoo says search is restored. It would not comment on cause.

Update 4, 1/3/15: A source says the crash was due to a “bad code update.”
