Unbearable server lag

[Goooood_]

I've been getting crazy server lag recently and it's been absolutely unplayable for me. Menus take 10 seconds to open, lobbies take forever to load, I keep getting ghosted and lagged back, and my ping spikes like crazy. It's been happening 24/7 and I just want to play the server normally again. I often get sent to limbo with a message that says "Out of sync, Check your internet connection!" (even though my internet is fine)

Is there any possible fix to this?
