Outrageous ping spikes for no reason

Can someone, preferably from riot, explain to me why over the past week I've been getting ludicrous ping spikes out of nowhere?

It's only in game too- Literally just got out of a game where I was going up to 4k ping every few seconds and I go to a ping test website, test to Chicago where the servers are and it's telling me 14. I usually play at night so that other people using the internet where I live won't have as much interference, but during the past week specifically even that hasn't been helping. What's even weirder is that usually the first 10 minutes is fine, my normal 15-30 ping because I live about an hour south of where the servers are. But then 10-15 minutes hits and I spike up to about 500 ping for the rest of the game.

I'm very tired of racking up what are essentially free losses because I can't see what's going on in time to react to it. 500 ping translates to about half a second delay not only on what I see, but also my cast times, and even though that doesn't sound like a lot it's enough to make the game borderline unplayable. Certainly puts me at a huge disadvantage. And it annoys me that it seems to be on riot's end, because my internet never goes below 5 bars during these pings spikes and I'm still able to load webpages fast and ace ping tests.

Did you guys reduce your server capacity because the season is about to end...? Is it this new, terrible client that everyone's complaining about? Are we ever going to get answers on the loading screen bug, which has also netted me a couple free losses that I could never have prevented in any way? Are any of us going to get compensated not only for our own lag and load screen issues, but also those of our teammates which also screw the game over?

Kinda frustrated with the lack of response right now tbh. [slayer-jinx-unamused]
