BleepingComputer.com: Can't access BBC on Opera, but can on Firefox.

Hello,
I am currently at college, and the Internet is filtered with 'Barracuda' (this may be significant, I don't know.).
I can access the BBC News site when at home on Opera, but when at college, i cannot access the same site with the same browser. When i switch to Firefox, i can access the site.
Does anyone know why this happens?
Thanks,
GB

If the filter that the school uses is the only difference, that's the likely culprit. I assume you would need to speak to someone at the school to confirm this.
