Slow loading specific web page

IliasTsoukalis

Hi there,

I have a weird problem with loading time on a specific site (http://www.mednet.gr).

The site makes a php GET call for a gzipped css file (http://www.mednet.gr/application/css.php?request=application/themes/mednet/theme.css&c=46) which takes about a minute to complete.

The weird thing is that I get this delay only through Sophos! Not with a direct connection or an obsolete TMG Proxy server that i tried.

I bypassed any checks on the site and used the browser developer tools to verify that I get no error on loading.

Bypass content scanning is enabled (if that makes any difference).

Any ideas??

    Hi Ilias,

    As you can see the delay is observed through the next hop routers, which clearly makes us doubtful that the issue is on the ISP side. 

    Thanks

    My TMG server is on the same ISP, has the same DNS Server and loads the site in 2s.

    The tracert actually shows that after 213.239.203.146 no response was valid due to a firewall barrier or smth.

    You can do the same test with an online tracert (http://ping.eu/traceroute/).

    What is located on 213.239.203.146? If there is a drop due to the UTM it will be logged in the packetfilter.log.

    Thanks
