Network filters are back again-partially

Well, the network filters that are controlled by some mysterious denizen of the internet access restriction office have once again cranked up the restriction levels from the job. For some unexplained reason, the filters that blocked all Blogspot addresses and many other "personal/opinion page" blogs had been relaxed for the past couple weeks, leaving free, access to my humble blog, the mighty Instapundit and many others that were previously blocked. But today, the filters have been tweaked, upgraded, tightened down again. All Blogspot addresses are again verboten. Instapundit remains available as do blogs that don't reside at Blogger, so I'm not completely blocked from seeing what is going on in the world.. But I suspect more tweaking in the near future.
