Well there's nothing you can do about it -- there was nothing on Riot's servers end that caused your ping spike as they are pretty good about immediately disabling queues when that happens (like 2 nights ago).
The problem is on your end whether that be with your hardware, your ISP or even someone using your connection. I've offered a solution that uses a minute of your time before every game. If you're not willing to do it that's your own problem. I have never lagged in over my 3,000+ games in League in 8 years now and that has been because I've ran that test since the beginning (I have however lost power during a game that sucked but can't be predicted).
