Honestly, Why Bother?
We have a small competitor who has, on and off over the years (they just re-did it) blocked access to their corporate web site from one of our offices. Like we can’t see it from our other offices or from home or from wireless air cards sitting in our offices. Honestly, why would you bother going to that trouble just to irk a competitor? I guess I’m glad that’s how they’re spending their available cycles.
