If you use either Bing or Yahoo, both services have been down since 2:04 PST on May 14th.   Bing is serving no results, while Yahoo – that is powered by Bing Seach – is running no organic results but is including their own shopping results, “____ from Tumblr” section and suggested searches.

Bing’s screen says:

Yahoo’s page doesn’t make any reference to the lack of organic search results, but instead displays this for searches:

Yahoo’s page still includes the “Powered by Bing” in the footer.

Siri Search is also down, as is using either Bing or Yahoo from a mobile device.

Bing and Yahoo suffered another outage earlier this year, when they both went down for 30 minutes in January.

We will update as more information becomes available.

Added:  Within 5 minutes of publishing, the search results are now back.  Total outage was between 25 and 30 minutes.
