That is so odd about your not being able to access DM. I'm sorry. Amid the trashy celebrity stories, near-total absence of investigative journalism, wildly vacillating slants and horrendous spelling and grammar, there are some truly informative photographs about many of the top issues of the day, including some stories suppressed in the U.S. media.
My suggestion at this point is to ask a friend with an Internet-capable device to come over to your house and see if they can access the site. If they can, then call your ISP provider and ask what's up.
