I am having some issues with the Telecom network. I'm often unable to access websites via browser, even though I can ping and tracert them without issues. DNS resolution is working fine, but it seems the remote server is unable to make a connection and times out with a "Connection closed by remote server". Using a remote proxy everything works fine, which leads me to think this is a Telecom issue. This has been happening more often recently and I'm starting to worry as internet access is very important to me.
What could be the issue? Here is an example with one website, www.minecraftforum.net (which redirects to varnish.cursetech.com) :

Seems everything is in order but attempts to GET the website fail, as the connection is closed after a while as the server times out. So it seems the connection request is making it through but the data is unable to be routed back to me, leading to the server giving up.
What could be the issue? Does anybody else have the same issues? Is there a way to fix it or do we just have to wait it out?
Also, on a related note, google.co.nz has become so unreliable (randomly timing out generally unresponsive) I've been forced to redirect to google.com which always works fine. I suppose this is part of the general problem as well.
