Try this unblocker!

It's new and nobody knows about it yet:

It looks like a lot of school administrator type people have been watching our sources, and are blocking new unblockers pretty much as soon as they're released. So all the unblockers we've posted on this site are probably blocked and any new ones we post from that same source will be blocked very quickly as well. For this reason it'd be best if you try to make your own unblocker instead - you can find instructions on how to do this here: How To Make A Proxy

How you can unblock web sites at school - Week 05, February 2010

We post some unblockers roughly every week, so sign up for our feed to stay updated!

The simplest way to unblock web sites at school is by using an unblocker. You can get to any blocked site this way.

Other ways to access web sites are by using sites that translate pages , for example Google Translate or Babelfish. Also try Google's cached copy of the site. However, it's not possible to login that way, so it's still best to use an unblocker if you need to login.

What do unblockers do?

Unblockers are like a gateway that pass information between the computer you're on and the site you're trying to visit. The unblocker visits the site you want on your behalf, downloads the page, and sends it on to you. So the site you're trying to visit never sees your IP. So actually you are browsing sites indirectly. Internet filters only see you accessing the unblocker, not the real site.
