Videotron cause Disconnect in League of Legends only?

Same issue here. Users on Facebook have reported contacting Videotron, and apparently they were working on a ticket, although they needed more people to report the issue to open a ticket with Riot (5 people, a lovely ridiculous arbitrary number).

I tried support myself, and was told I would need to contact Riot Games myself and that there is currently nothing they can do until then.

I am shocked by the excessively poor response to this situation. I have no word other than pathetic. I'll give it a day or 2 for them to at least acknowledge the issue and confirm they are actively working on it, otherwise I'll also be shopping for a new provider on this Black Friday.
