All the main UK and Irish ISPs get blocked every time there's an EPL or CL (Champions league live games) being broadcast - and as far as I can remember this is the first one to severely hit this service this season because usually our workarounds can bypass the regular blocks.
Until today. At the moment have managed to reroute some channels to different servers so Sky Sports Main Events and Premier league channels should be clearing..
Will update again here tomorrow but for now, it looks like UK ISPs have successfully blocked most of the UK channels for today. The blocks will normally be turned off a few minutes after the last live match finishes - so approximately 8pm UK time.
