Higher Ping Than Usual?

I've recently been experiencing a ping consistently about 50-60 higher than usual. I've run internet speed tests and they tell me my connection is just as good as it's always been and gives me the ping that I usually get. But when I get into a League of Legends game, my ping goes up and sits consistently 50-60 higher. This has been going on for several days now. At least that I've noticed.

Anyone else experiencing something similar?
