LoL Esports Youtube Channel - Vanished?!?

Just wanted to catch up on a bit of LCS and searched youtube for LoL Esports - No channel comes up like it used to - some of their videos from a few years ago are still there but the channel is gone I tried accessing the channel from one of their old vids but it says "There is a problem with this channel network" It's not my internet because other channels work fine - I wonder if this isn't an individual problem - is the channel down for some reason? thanks
