ISP Policies

Thu Sep 9 05:44:11 UTC 2004

Once upon a career, I was involved with shipping cargo via ocean vessel 
to Kuwait (and other Arab countries). We had to provide signed 
affadavits from the ships owners that the carrying vessels were neither 
Israeli owned nor would call any Israeli ports during the voyage.

If Arab countries' ISP's were to follow the same political philosophy, I 
could see them filtering accordingly.

In short, politics.

Is it 'normal'?

Boy, is that a loaded question ;)
