Yesterday, I followed up a link from Glenn Reynolds and discovered that the conventional Volokh Conspiracy url: www.volokh.com was working just fine again.
Last month, it was impossible to access that eminent legal blog using that address from several East Coast computers. My theory was that someone with a grudge against that blog had distributed a Trojan which overwrote that address in the Hosts File. I was planning to edit my Registry one of these days to fix the problem, but then Glenn Reynolds mentioned hearing about the problem, and identified an alternative working URL: www.Volokh.Powerblogs.com, eliminating the need to go to all that trouble.
I’m glad the issue is gone, but I wish I knew what really happened.
