Ping failed to return time

[RelaxLiu]

Ping what is the reason for the return of a domain name that does not exist?

github.xxx//favicon.ico?1504163468779:1 GET https://github.xxx//favicon.ico?1504163468779 net::ERR_NAME_NOT_RESOLVED
error 12
error loading resource

this 12 Why would you return?

Hi @RelaxLiu,

The favicon might not always exist on the server, but the client will attempt to load it anyway and return a response time either way. Err is returned if the favicon didn't respond.

See: https://github.com/alfg/ping.js#notes for my note on this method.

If there's a better way to do this, suggestions are welcome!
