Line: 9 Column: 1 - 74
"...9/2014--> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <met..."

Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.

Line: 9 Column: 1 - 74
"...9/2014--> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <met..."

A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.

Line: 9 Column: 1 - 74
"...9/2014--> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <met..."

airnow.gov Ping

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source.

airnow.gov TRACEROUTE

Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop is a measure of the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated.
