Errors
The character encoding was not declared. Proceeding using “windows-1252”.
"......"
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
"...TYPE html> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en-GB" dir="ltr"> <hea..."
Changing character encoding “utf-8” and reparsing.
"...lse" /> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <me..."
Changing encoding at this point would need non-streamable behavior.
"...harset=UTF-8" /> <meta name=..."

iop.org 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.
iop.org 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.
