First impression when I got here, our main contractor changed their network configuration. They add some internet policy control to control their users to use the internet. I was thinking, ah at last, welcome to the end of slow network connection, I say horray for bandwidth and content management! From what I heard, they ask IT technician from their main head quarter in Japan to set it up the network. But in reality, the internet only good for several days, then it went hell again.

A lot of sites and ports already blocked, now the users are really limited, because they employ some TCP proxy system, which intercepts HTTP and HTTPS ports, which automatically redirect users to login page before they can browse the internet. This automatically disable the use of IM/P2P clients, or any other internet applications which not browser based. They intercept the TCP port, modify the contents by using 301 redirect to login page, after login go to the intended site.  But I’m not sure why I got connection problems often, usually happens during in the lunchtime, all the way to the 7pm. In the morning usually OK. During normal speed, usually the latency to the outsite world is about 700-800ms, but when its bad, it can go as high as 10 secs with 90% packetloss, and from the traceroute, it already happen on the first hop from my computer. The first hop still in local network, because during normal time, the pings are not more than 3ms.
