Flickr stats from the Flickr blog
Some interesting statistics:
• The number of images uploaded has tripled over the past two days, January 1 and 2
• Normally we serve about 15 million photos a day, now were serving about 30 million
• About 20 images are uploaded very second; when an image is uploaded, processing it takes a few seconds, because 5 images in different sizes are made, and because we keep live backups on site, each image is each saved onto two different servers"
