Facebook Reaches 500 Million Users

Facebook announced today that 500 million people are now using the social networking site. Along with hitting a new milestone, Facebook reminded users of the few big numbers the company deals with on a daily basis:

  • 100 billion hits per day
  • 50 billion photos
  • Two trillion objects cached, with hundreds of millions of requests per second
  • 130TB of logs every day

In a post on the Facebook Engineering Bobby Johnson said, “We’re very proud to have built a site that 500 million people want to use, and a site that still works with 500 million people using it.”

He added, “But this is really just the start. We’re hoping that in the not too distant future there will be another 500 million people, and that these principles will help us overcome whatever new challenges arise on the way there.”
