they use the same CDN providers as all the others -
Akamai, Limelight and Level 3.
I don't think Level3 is anymore in the picture;
as I recall, it was exclusively used for one of the FlashHD
tvmodes and L3-hosted streams were the first to be axed
when stream management was delegated to "Video Factory";
an Akamai-hosted FlashHD stream remained available
for quite a while afterwards, until someone at the beeb
belatedly pulled the plug on it, as well as on the Akamai-hosted
"legacy" HlsHD streams (effectively killing all sources for
the 720p25 TV mode :-( ).
And apart from commercial Akamai+Limelight CDNs,
BBC manages its own BIDI CDN, for clients within the UK:

A quite interesting source of BBC iPlayer related
tech info (aimed mostly at coders) is
https://iplayer.engineering/
From there, certainly worth reading:
