Nah, this is the best explanation from a reddit thread, looks like it was pinging heartbeat.belkin.com to verify network connectivity after getting DNS servers from DHCP: http://www.reddit.com/r/technology/comments/2ik43h/belkin_firmware_update_1072014_crashing_many/cl2u41n http://www.reddit.com/r/technology/comments/2ik43h/belkin_fi... 10:40 AM <Duiwel> Just got an e-mail from someone on our Wireless ISP mailing list: We found the routers are sending icmp to heartbeat.belkin.com. Even though we could get a response here at our NOC, the belkins are not receiving it. We added the ip for heartbeat.belkin.com as a loopback address on a router on our network and it becomes 10:40 AM <Duiwel> reachable to all the belkins on our network. Lo, and Behold! They all work again. 10:40 AM <Duiwel> May have to try that
