When you blog, it’s essential to tell others that you have updated your blog. The Update Service in WordPress is the service that helps you do this.
Update Services process the ping and update their proprietary indices with your update. Now people browsing sites like Technorati or Sphere can find your most recent posts!!
By default, WordPress sends a ping to:
https://rpc.pingomatic.com/
