Server Sentries Block Me

for over a week, I have been unable to access my blog, and all other direct wordpress blogs on a particular computer.

Every wordpress site says “Lost? Our server sentries tell us you should not be here.”

This is very annoying, because I would like to update my blog, but have to use the computer at my workplace because the computer at home is blocked.

Why? Is my IP blocked? And why would it be? I am admin for my blog. I would love for this issue to be resolved.

Much thanks!
