So there are a few things at play here:
- General network issues with big ping spikes and small amounts of packet loss. Not exactly minor, but not as bad as things are now.
- The occasional DDOS attack (rare but they happen).
- Weird routing problems where your ISP decides to send your packets on a road trip. Really hard for us to diagnose, but we're also working on this as well.
- A new issue with this update, where server bandwidth is getting throttled causing huge amounts of packet loss.
As for #1, we've been improving on this quite a bit with the past few updates and hotfixes. #2 is something we're looking to mitigate more with the UE4 engine upgrade we plan for the next patch. #3 is something that we haven't been able to diagnose, but we're looking to see if there is something we can do on our end (we're not sure if there is though). #4 is new and we're looking into it, but we're working with our server providers to diagnose the issue and fix it ASAP.
