Getting two different results pinging seneca.systems from a Comcast home service address and a server at Rackspace (ORD1, I think).
Yesterday I got similar results and couldn't access the site in a browser; today the browser is successful (!), but pings are as below:
10:12 ~[ruby-2.2.2]$ !406
ping seneca.systems
PING seneca.systems (54.204.1.127): 56 data bytes
