The photo-sharing site tried to make the best of a data center upgrade by getting its users to share what they're doing during the outage.
Trying to make lemons out of lemonade during an eight-hour Flickr outage, Yahoo tried to rally its fans to engage on Twitter and Tumblr instead.
The photo-sharing site planned an outage from 9 p.m. PT Thursday to about 5 a.m. PT Friday, publishing its traditional "bad panda" outage notice. In the meantime, Yahoo fired up the WhileFlickrIsDown Tumblr and the #WhileFlickrIsDown hashtag on Twitter.
"Check out http://whileflickrisdown.tumblr.com/ and let us know what you are doing #WhileFlickrIsDown," Flickr tweeted, pointing to a form to submit entries for the Tumblr blog.
Why the outage? "After five years with only minor updates to our infrastructure, we are performing important upgrades and moving equipment to highly energy efficient data centers," Flickr said.
