if it was DNS you would get a 404 if its timing out its probably cause someone is packeting them.
no, because for a 404 error, apache (or other webserver) has to be reached, however, you can't reach them if there's a DNS error, i.e. the IP for the main server cannot be found.

So you'd get a DNS error, not a 404. Just a slight correction

Anyway, hackers.com is for lamers, don't go there, everyone there is a fag and a total loser IMHO.
