From a Dish Network forum:
We have a tech on a roof with a Spectrum Analyzer.
He says there is nothing at orbital slot 129. Just noise floor. The lights are out.
Out in Denver as well, DISH Customer Service number is just busy.
It looks like the satellite at 129 may be toast - I can still get some channels like 299 and 300 from 110 and 119.
This is per dish's facebook page...
We are currently experiencing technical issues with the satellite location 129. This has caused signal loss on some channels. We apologize for any inconvenience that this has caused our customers and we are working to resolve this issue. Please direct any further questions to our DISH Answers facebook page or send a private message to DISH Answers.
