I assume we are discussing here the "Segment not found"
issue plaguing the hls tvmodes (and not the audio artifacts
described as "blips" by C E Macfarlane in audio downloads,
earlier in the thread...).
Well, there aren't OTHERS! All the flavours of the hls
tvmodes (hldhd, hlsvhigh, hlshigh, hlsstd, hlslow) are
hosted/streamed on the same Akamai CDN, whose
The hls tvmodes are the default in GiP 2.95,
thus causing grief to GiP 2.95 users!
One other thing; according to the commit comment at:
> HLS stream corruption has spread to radio
it would appear that radio downloads (hls radiomodes)
are also affected; I haven't noticed such a report in the list/forum
about "Segments not found" during audio downloads,
possibly because the default radiomode (320k in the UK)
uses MPEG-DASH streams.
The hls radiomodes are hosted/streamed again
on a unique Akamai CDN, whose hostname is:
again being (supplier="akamai_hls_open")
To conclude, inform your BBC liaison that
it is the "akamai_hls_open" CDN/supplier
that is misbehaving currently (since the start
of the month...).
