By default, WordPress will ping to rpc.pingomatic.com which in turn pings other services. It is a good idea to have your own list of ping servers so that you reach out to more sites. Here is a list of ping servers you can add. This list was put together in 2010.

To update your ping list, go to Settings -> Writing options in WordPress control panel. Add these servers to Update Services box.
