net/http Get i/o timeout

[ldaponte]

I think the timeout is happening while Get looks up the IP address - substituting the fqdn with the IP address resolves this issue. I confirmed I can lookup names without error. Setting the client timeout to 30 seconds did not help using the code:

    timeout := time.Duration(30 * time.Second)
    client := http.Client{
            Timeout: timeout,
    }

    resp, err := client.Get(fmt.Sprintf("%s%d", gaugeUrl, gauge.Id))
