Yes, Yahoo. I'm not going mad (at least, not yet... Or not completely mad).
I've tried figuring this one out myself but to no avail. I sometimes spy on what the programs on my machine are doing network wise, and I noticed a while back that iPlayer streaming connections were beginning to come and go from different IPblocks. I thought nothing more of it at the time, just made a mental note of it. I began to notice this around the time of the LHC switch on day, and the week afterwards - that's when the addressed IPs began to appear to transition to different ones. However, the other week, I was listening to some BBC7 shows and noticed it again - the content was coming from a noticeably different netblock. Being the geek I am, I did some tracerouting. Here's the results of two traces. The first IP is one which I'd seen associated with iPlayer stuff for a fair while, so assumed that Akamai were being used directly by the BBC to cache-and-forward content more efficiently to ISPs like mine.

Both of these IPs have served me iPlayer content through the streaming interface direct from the /iPlayer site. How come more and more of the stuff I stream (radio and TV, but I've been Listening Again a fair bit in the past couple of weeks) seems to be coming from these non-BBC netblocks? Both of those traces are from my Be* connection (first hop is the gateway, ICMP responses are QOSed to lowest priority) but I've seen this strange behaviour when streaming over my parents' Zen DSL connection too. These IPs are *definitely* iPlayer streaming servers; I've confirmed, double- and triple-checked with Wireshark and various other tools which let me see in realtime what's connecting to where and when (which is nothing very complicated these days!) What really got me was the second IP resolving to *.Yahoo.com hostname... /Why Yahoo?/ I don't see the link at all. Can someone with a clue help me out here please? - Sent via the backstage.bbc.co.uk discussion group. To unsubscribe, please visit http://backstage.bbc.co.uk/archives/2005/01/mailing_list.html.
