If you have the engineer's toolset on our system, you can enabled browser integration on your account in Manage accounts, this will bring up tools on he Node details page that include a ping, which will ping the node in question. Otherwise, you'd have to customize the html of one of the resources to try to add a ping option similar to the telnet and web browse options in the Node Details resource on the page.
