Blocked at the Pass

At the end of the work day, while still at school, I logged on to the internet and googled wikipedia. Up pops a huge black and red square saying that this page has been blocked. What? So I decide to check out my blog. Again, a huge black and red square blocking me. I'm beginning to see a little black and red. I know that it is their computers and their dime, but it was on my time. In the past any adult, could access those not-so-appropriate pages at school. Wonder if they can still do that, and I can't get wikipedia?
