Why Islamic websites are not avialable on the computer network ?

More than likely it's because that the "Islamic Ideology" is so contrary to Christianity and western social mores that they are either banned, shunned to the point where no one will advertise or support them and who the heck wants to watch Imams going on about how the Jews are "Apes and Pigs". What infidel wants to turn on their computers or television or radio to listen to an idealist of Islam tell them how bad the "infidels" are?

Personally I don't know of any solutions but I sure as hell hope that there isn't. It's best "To let sleeping dogs lie".

Presumably you are accessing the 'net via a private organization, or you have a really bad ISP who thinks it's acceptable to discriminate, or whomever owns or manages the computer you're using has put a filter on it to prevent it from being able to browse to those sites.

Here's my favorite Islam-related web site. Hope you enjoy it and find it as informative as I do. You can always find news and articles about Islam's latest contributions to world peace and the betterment of all mankind at http://www.thereligionofpeace.com/ .
