Disconnected from ranked game - no option to reconnect

I've tried closing the client and re-opening, the rejoin game option just doesn't appear. I can even search for a new ranked game to play, as if the one in progress doesn't exist. When I click "Live Game" on (http://na.op.gg/summoner/userName=iAmTheBreast) it shows that the game does exist and I'm still in it, but there's nothing like that on the actual client.

Also the disconnect itself showed my ping at constant 500, but there was nothing wrong with my internet.

I'll update when I find out if this game will show on my match history, and whether or not I lose LP from it

SO the game still showed as active in naopgg for 35 minutes, up until starting a new ranked game. Doesn't appear that I've lost any elo and the game still isn't showing in match history, so I figure that everyone else DC'd the same time that I did.
