What causes the extremely high package loss?

@ApyhsApex is using a hybrid cloud solution, which is a mix of bare metal and public cloud. Most, if not all of these servers are from Google, AWS and Azure and located in big data centers. It's not EA's problem to fix the network issues of these giants, all EA or Respawn can do is to escalate the issue to Multiplay and the latter to their service providers and so on. Sure, there are times when there is faulty hardware or software in the data centers and those are the moments when it's not on the client side. But most of the times (like 90-95%), the faulty hardware / software lies somewhere along the connection and this kind of is on the client side. Each client that has problems needs to check if everything on his end is OK and escalate the issue to their ISP if problems are persisting. It's not EA's nor Respawn's job to deal with your ISP or their respective providers. Most they can do is to guide you towards isolating the cause of issues through their connection troubleshooting process.
