If you're one of the people who prefers to disallow Technorati's bot, which does not respect the robots.txt convention and it's directives (talk about a good net citizen...), you may have resorted to blocking the bot's IP, 126.96.36.199.
As of today, Technorati has changed the originating IP of its crawler to 188.8.131.52.
Update your block-lists accordingly. ;)
(I don't currently block TR myself. I enjoy the blog-ego hand-job it provides... when it works. ;)
