That's my next experiment. cf below...

Yes. The speed seems OK. Both here and when I get Richard (i.e. My service
provider) to test from his end of the 'pipe'.

Indeed, I did a test and tried running two fetches on two machines in
parallel. Each ran at the same speeds as if only one were running.

Normally, video comes at about 50 Mb/s. Presently it is more like 7.5 Mb/s
(per fetching stream) so I could do a number of fetches in parallel if
needed!

However radio (audio) fetches run at more like 14 Mb/s which is more normal
here. 

So it does look like a CDN problem. The curio being that it was fine until
a couple of days ago, and that no-one else seems to have had the same
change. I'd not altered either the fetching command or anything else I can
think of that might be relevant.

All being well, I'll know more shortly. Currently doing other things (like
email catchin as here!)
