After an interruption over the summer break due to problems with NASA’s border router, the UCTV International Services are back on air (much to the relief of our clients across Europe, North America and Australia). It appears that a misconfigured system somewhere in the US was rebroadcasting our program guide list (called Session Announcement Protocol, or SAP, Announcements) in such a way as to deny NASA Internet access by overwhelming its border router. Our thanks go to all the engineers on both sides of the Pacific who worked on solving the problem, especially the UC Berkeley engineer who identified the errant box (which wasn’t on their network) and organised for it to be shut down.
