I went to the itunes store to check out their podcasts. The podcast pages show up in itunes, but all the 'subscribe' and 'get episode' links are grayed out. itunes help pages says that'll happen if the site hosting the podcast is unavailable, so does that mean the entire itunes store podcast system is down? Or is there something wrong on my end? I'm currently logged into my account with itunes, and I just bought something off itunes yesterday with no problem.
