Same, I've been getting ridiculous amounts of Ping, I feel like I'm on the US servers despite living in the UK.

@d3adst1ck Sounds good, much appreciated

@mos409311 Have you tried disconnecting every other device from your network to rule out a local bandwidth hog? If not, I'd check that first and if the spikes go away start reconnecting devices until you figure out which one is the problem. Check your router also to make sure it's not being overloaded.

There shouldn't be any spiking. For example, my home connection where I game from is a consistent sub-100 ping to all US data centers but if I try to do that from a much busier network in a different location, it will spike occasionally.

You could try contacting Rare or Microsoft support with the information and see if they can help you out? I'd make sure you exhaust all local options at troubleshooting and provide evidence that you did when you contact them though, or you'll likely get a canned response with generic troubleshooting.

@d3adst1ck Seems like my "average latency" in all US regions spikes from 70 to over 1500 every couple of seconds. What exactly does one do with this information?

I experience the same. Ping frequently got up to 500+ making the game unplayable for some seconds.
On a server yesterday everything was fine till a reaper chest spawned (= a 3rd ship enterd the server)

My guess is that there is something wrong with multiple ships beeing on a server or it has something to do with a player cheating and the cheat tool requesting bigger data packages from the server frequently, causing the server to stutter.

This looks like packet loss. Packets get lost either being sent to the game server or coming back from the game server. The local simulation runs until the server says 'no, this isn't correct' and you receive updated world data which rubberbands you back to where the server thinks you are.

Network performance in other games means very little unless they are in the same data centers and you get the same route from your PC to that data center because it could be some node along that path that is causing the problem.

You could check for weird ping spikes here: https://www.azurespeed.com

You can also get the data center IPs from there and run trace routes or use other better tools to see if there is any packet loss or connection jitter.
