No SD Channel 4 channels except for Film 4 and the 4 Music channel co-owned by Bauer which has a different playout.

HD channels on Freeview aren't affected.

Sky/Freesat don't appear to be affected as I can watch C4 SD on Zattoo Switzerland.

SD Channel 4 channels still off air at Crystal Palace! Been about an hour now! Suppose it's hard to get an engineer this time of night!

Still no acknowledgement of the fault by Channel 4 on social media either.

They have had Clare Balding mention it on air, that it's "fine on HD". No good of course if you can't see her saying it in the first place, or can't get the HD version anyway.

Yes just found that Tweet hidden away on the Paralympics feed.

I can get HD Freeview and Sky on my main TV but the one in my bedroom just has SD Freeview so can't watch in bed. Might as well go to sleep!

C4 SD on Freeview is still off-air.

I'm fairly sure Arqiva don't run the whole network totally unstaffed overnight

If it's just Channel 4's services affected then it will be a problem with the London multiplex rather than the actual transmitter.

Although I believe that in the case of the Digital 3&4 Mux the multiplexing is now done at the transmitter sites rather than at a central location

Can't switch to either Channel 4 SD or HD on YouView currently. The current Paralympic Programme isn't active in the tables of the EPG. It's Greyed out.

Hope this link works. (Link to DITALBITRATE's scan of CP/D3&4)

Film 4 present, but no other C4 channel.

Can you explain how it was only those few C4 channels that went blank and not the whole mux? Assume it was nothing to do with anything at Horseferry Road otherwise other transmitters would have been affected too.

I'm not sure Horseferry Road is involved at all, Channel 4's playout is at Red Bee (now Ericsson) in W12

Remember that they'll be supplying a different version of C4 for London, and the London version of the Mux doesn't go anywhere else.


Without knowing how that mux is put together, it could be any number of things. Seeing as the services seemed to totally disappear off the Mux it suggest it's not a playout issue. Maybe a failure of some encoders or a configuration issue, maybe those services share a circuit and that failed?

Ads just failed. Thanks to live ca she covered well. The slide look like something from the 80s with "programmes continue shorty "
