Microsoft Code glitch

Did someone hack their site or is it a problem from their end?

I showed it to my friend and put it as hacked by his name and he got scared like hell

Zune ZIP code glitch persists in Washington, D.C.
Zune owners in Washington, D.C., might be out of luck if they want to use the related Zune Marketplace online music service. An apparent glitch is keeping people from signing up for the service with credit cards that have billing addresses in any one of four Washington, D.C., ZIP codes.
The problem itself isn't news. It was noted by the Washington Post's Rob Pegoraro in this November review and acknowledged by Microsoft in December on this support page. Granted, it's not a huge swath of the country, and it's only one area of the city. But the weird thing is that the issue appears to have persisted to this day, unexplained, several months after the Zune launch.
A reader from Washington, D.C., Jake Plane, wrote in an e-mail this morning that he has been dealing with this issue for months, since buying his Zune. He has tried repeatedly to sign up for the Zune Marketplace service, including twice today, to no avail. He wrote that Zune customer service representatives have been "very, very kind and patient -- but have no solutions for me. It's kind of like going to a doctor with a fantastic bedside manner who unfortunately has no actual medical advice to offer; it's nice but kind of useless."

I'm not sure why they would not fix the issue even after so many months.
