How do I unblock sites blocked by DET's proxy 9202??

Try Hotspotshield VPN. It's one of the most popular consumer VPN with other 120 million downloads. It has a free (ads-supported) as well as a paid version.
The free version has annoying ads, but otherwise works very well to unblock YouTube as well as secure your Internet communication so that noone can track or spy on you.

This depends on many things really. Where are you trying to unblock YouTube from, and why is it blocked in the first place. There are a few websites and programs that allows you to do this, but it really depends on where you are to how you go about unblocking it.

You could try to use a proxy server, like freeproxyserver.net, however if you are at work and Facebook is blocked, then they likely blocked the proxies as well.

Lets admit it, we all are crazy about Facebook and can't live without it. We love following friends and messaging them as well to know what they are doing right now.

But unfortunately Facebook is blocked in many places specially in schools, colleges and offices and to unblock facebook, you need web proxies, lot of web proxies.

And this is where we are going to help you. On Our website http://mwolk.com, you can find 100's of web proxies to unblock Facebook and other such sites like myspace and youtube.

How to unblock Facebook
You just need to find web proxies which support facebook (check below link of ours to get the list of such proxies). Though please note that many such proxies may not support facebook (proxies have smaller life as the get blocked fast), still even if 50% sites are working, I think that's good enough.

Check with your IS/IT department and/or your HR department for the company policy regarding the use of social networking sites.

I suspect your IS/IT department has these sites blocked for a reason. In addition, most have software that tracks an employees internet usage.

Attempting to bypass these security features could possibly result in disciplinary actions or worse.

i have never seen that, but have you tried hidemyass.com, it is an online proxy, i know you dont want to use a proxy, but it does not require any config on your PC, just go to the website and then browse from within the website!!

You'll very rarely find Proxy/unblockers sites that are unblocked.
If you find a website that's meant to be blocked, but isn't blocked yet, it'll soon be blocked!
A few months ago, my friends found a website that'll let you go on any website, Facebook, Myspace, & Redtube, but within a week of the website being constantly used, it was eventually blocked! :(

What you need is a teacher's net account, or a tafe account.
