Started about 4 days ago. works fine most of the day and then randomly get massive ping spikes. i go from 100 to 500-700 ping and any time i put some sort of input or some sort of effects are happening around me it will shoot up to 1-4k ping for like 10 seconds and the drop back down..... then go back up. Lasts for an hour/hour and half on average and then goes back to normal. Also get constant disconnects. Its not from me, my internet works perfectly fine. Sounds extremely similar to the issues back from the March DDoS attacks

I know its not only me because a friend has the same exact issue that happens at the exact same time. He also lives relatively close to where I live so maybe its only affecting certain regions/players?
