Some errors started occurring on a site, so I wrote this instant test routine.  It does absolutely nothing and when I review the source code, it is blank.  Any idea what could be causing it?
<!DOCTYPE HTML>
<%
Response.Write    "<html>" & vbNewLine & _
    "    <head>" & vbNewLine & _
    "        <title>Testing 123</title>" & vbNewLine & _
    "        <meta http-equiv=""Content-Type"" content=""text/html; charset=utf-8""/>" & vbNewLine & _
    "    </head>" & vbNewLine & _
    "    <body>" & vbNewLine & _
    "        Testing 123" & vbNewLine & _
    "    </body>" & vbNewLine & _
    "</html>" & vbNewLine
Response.End
%>
