It appears that any site, that start with "http://mobile." are gone.
If you delete the "/mobile.php?UMPG=index" off of the end, you get a version of the site.
They will be different than the other ones.
Sorry for the confusion but there is some good news.
The links that start with the numerical address appear to still be good.
Also found another link for the Chicago Sun-Times http://188.8.131.52/mobile.php?UMPG=index
and there is no sign in with this link.
