Ping spikes random times throughout the day ( Miami, FL)

Hello, I've been experiencing ping spikes for the last 3 months and its driving me crazy. I'm getting ping spikes on most applications such as discord and get ping spikes in the games I play. Im not too tech savy on my downstream and upstream levels so I don't know how to evaluate them.  Here are the pictures to them https://imgur.com/gallery/45c8LO5. In the game that I play the most which is dota 2 I usually get around 40 ping , but for the last 3 months Ive been just getting non-stop spikes. Here is the ping plotter for the dota 2 servers https://imgur.com/6UUePyu. Would appreciate any type of help.
