The site tracks not football matches, but when blocks occur, and, right now, there are not any.

(The whole joke about the site is trying to detect football happening via internet blocks, as otherwise myself personally I wouldn't know at all otherwise about matches happening)

> I'm guessing it's specifically because it isn't a La Liga game, it's UEFA Champions League

Probably just a matter of time. The article mentions:

"Lo bloqueos aplicarán "todos los días de emisión de eventos deportivos en directo", arrancando por primera vez con el partido de eliminatoria de la Champions League entre el Atlético de Madrid y el Barcelona que se celebra hoy martes 14 de abril."
