@Jdark None of the RTL channels are gone overnight, I read that the “ normal ” RTL degraded NFL to its channel Nitro (a channel of the RTL group) at the beginning of december, so you may take a look at the “ Nitro ” schedule. If you speak german you can read this here, either way Swisscom did not remove any RTL channel.

So I checked for you NFL is running this night on the channel “ Nitro ”.
