[outages] Parital iTunes Podcast Outage?

Hi, Is anyone seeing a partial outage of podcasts using iTunes on a Mac? Several of my subscriptions have not updated since the day before yesterday and the subscription shows an explanation point inside the circle by the podcast name in list view. Running Wireshark and doing a "refresh podcast" on those individual podcasts, I see a successful TLS connection followed by a series of HTTP RSTs and the connection being torn down. Examples of podcasts not updating include: *KQED's Forum *NPR Topics: Technology Podcast *60-Second Science (SciAm) *Discovery (BBC) My other dozen or so podcasts are updating normally. Any ideas? TIA! JK
