IS THIS A JOKE?! NOTHING was done to fix the netcode.

Have you ever traced the route your ISP takes to the datacenters?
Come back when you have ruled out that part, then we may be able to discuss a local problem?

As said earlier there's a huge swimming pool between myself and the datacenter, unless I derp myself and I can dodge 95% of the things just fine and so do a lot of people in my FC, which are mostly EU players.
I don't use a VPN, and many of them don't use one either, those that do know it's a problem with their ISP.
