Match history seems to be down.

As the title suggests, I cannot view either my own or other player's match history. When attempting to view my own, there is nothing, but the blue loading wheel. When trying to view another player's match history, I get an error saying that the client couldn't connect to the match history service. I've restarted and repaired the client, and restarted my PC, but it that didn't fix it, so I'm guessing match history is down as a whole then. OP.GG throws an error when trying to update my match history as well.
