You are not helping me but the community. I am not a helpless person asking
for your help.

completely isolated from the Internet"
That is the only valid answer to the OP's question because perfect means
complete not "99.9999%" (which is really just another random number creating
a false sense of high security).
I am not going to dissect previous posts yet again and I am not interested in
your endless juggling with rhetorical tricks.
