Can we check availability of internet from sql Script? I google'd a lot with no use.

Any suggestion regarding this is highly appreciated.

You can do this with a SQL CLR UDF. Here is an example:

[Microsoft.SqlServer.Server.SqlFunction]
public static SqlBoolean HasConnectivity(SqlString url)
{
    try
    {
        if (url.IsNull)
        {
            return false;
        }
        var httpRequest = (HttpWebRequest)HttpWebRequest.Create(url.ToString());
        using(var response = (HttpWebResponse)httpRequest.GetResponse())
        {
            //Make sure the Http Repsonse was HTTP 200 OK.
            return response.StatusCode == HttpStatusCode.OK;
        }
    }
    catch
    {
        return false;
    }
}
