Why am I not getting anything back when I 'ping' certain domains?

Adam from Hesperia, CA

'Pinging' is a method of directly contacting a site just to confirm there's a connection there. According to the chatroom, if he has too many devices on his FiOS router, it could be preventing the router from connecting temporarily. Each device takes up an entry on the NAT table (Network Address Translation). Size limitations on that NAT table could cause the router to choke.
