Sao Paulo Server latency

To me, the problem of "that character is not online" is STILL an issue.

Just logged now and tested it. Stood in my hideout and for the first 5-10 minutes it was all ok, but after 20 minutes or so, I received a party invite from a guy who wanted to buy an item from me saying he couldn't whisper me before because it kept saying I was not online.

I don't think it needs a MTR test since I'm all fine with ANY other gateway, despite the latency problem (60 to 180ms gives us totally different experiences), just to update the social problem about this gateway is STILL an issue.


I'm still investigating this problem. Unfortunately, I have been unable to reproduce it myself, which is making it harder to find the cause.
Thanks for the extra info - I'm now able to reproduce the chat problem.
We've found the cause of chat messages not being delivered. We should have a work-around in with tomorrow's patch.

Was this addressed in the 3.3.0d patch??? Did not find any related note...

At least by now it seems to be working fine.


It wasn't a part of the patch, but included backend changes that required a realm restart to take effect.
Please post a WinMTR capture to br.login.pathofexile.com and I will take a look to see where stuff needs fixing.

Predictive mode is the equivalent of the netcode that most modern games use. Lockstep is only good when there is a reliable connection.

Fitzy, did you miss my WinMTR by any chance? It's in the previous page (59), I managed to get the readings when it was all ok, then a few seconds before the disconnect, and finally when it returned to normal some hours later. It's in page 59. ( https://www.pathofexile.com/forum/view-thread/1917103/page/59)

According to the /logs/Client.txt file, After the disconnect the login server changed from br.login.pathofexile.com:20481 to br2.login.pathofexile.com:20481

However br2's last traceroute ended in this random website "mx66.vagasnewsletter.com.br"

What is wrong with the gateway, man? This is actually silly, you need to change the Gateway's ISP fast!! This one is plain bad.


I've gone back and had a look now. When you're having issues, it looks like packets are being dropped between c91180fd.virtua.com.br and as16735.belohorizonte.mg.ix.br. If this is continuing to happen, we can raise it with our host, but it's a quite a few hops before it hits their network.

Re: login servers - you can randomly connect to one of the two when your session is handed back to the login service.

Re: that hostname, I think this is just some reverse DNS record that still exists for someone who used to control that IP address - it can be ignored.

This provider is giving us significantly better performance to our last. They're more responsive and are happy to help with connectivity issues if we get troubleshooting information to forward to them. Swapping has not made Brazil's internet infrastructure any better, so this is probably going to continue to be something we have to deal with to a varying degree.

I'm having similar issues with frequent disconects, always preceded by huge ping spikes(from 30ms to 1.4k).

Plyaing on both of the US gateways feels better, even with higher ping and some rubberbanding, but there's no disconects.

I've done some data collection on our end, and I'm not quite sure what's causing this.

There might be something weird going on between your and your ISP. I see a latency and packet loss jump on the last hop to you from the Brazil gateway. This doesn't show up from when tracing back to you from the Washington D.C. gateway.

I'll PM you a link to the data I gathered. You should be able to send this through to your provider with the ones you collected to give them a more detailed picture of what is happening.
Can I grab an extra couple of WinMTR captures to br.login.pathofexile.com? I need some to forward through to our provider to have them investigate.

Is this still happening? I'm seeing an average of 44ms latency to you now.

Hi there.

Today, at 15hs UTC, I was disconnected and after that all instances are having high latency. Right now it's 17hs UTC and the issue is still there.

My normal latency is 47ms.



Is this still happening? Tests from the gateway to you show around 30ms delay now.
