I have spoken with a few friends today that were having trouble with STVs, ITVhds, etc, 4 of them are with the same provider , whom I speak with via emails, as I use him for Eurosat line, upshot is that he was able to give out a new line, now the channels are working again, this has happened in the last half hour, so its worth asking your provider if he can do this, if he cannot then you should look for a new provider.
