I was just made aware that many people are having issues getting the MacCast from Libsyn. Listeners are reporting getting connection failures and timeouts. I was just told this seems to be a symptom of a larger issue. There is currently a battle raging between two tier 1 ISPs (see this cNet article for details) and is is resulting in large Internet “blackouts” for many sites and customers. The major group affected seems to be Earthink and Time Warner Roadrunner customers. If you are unable to get the MacCast your options are to wait it out or Libsyn has been attempting to work around the issue by updating information on their servers. If you would like them to try and route you around the issue you can send your IP address (if you are behind a router they need the IP from the router) to email@example.com. Sorry for the inconvenience, but it is not in my control.
