For the past 2 weeks there have been quite a lot of issues with Guild Wars it's connectivity.
I am currently looking into this to try and find out what is going on and how we can solve it.
Right now there are 2 problems:
-> People not able to get past the launcher / Connecting to ArenaNet
-> People that are having very high pings
For both issues I currently have a support ticket open and I hope to get it to the right team.
In order to diagnose even more I am working on a PowerShell tool, hopefully that will be up soon (I will post it here) - I have quite a bit of networking experience (went through CCNA 1-4), so hopefully I can deliver the right information to support.
The first issue is most likely an issue with Amazon's CDN (Cloudfront) - which makes it hard to troubleshoot since a CDN has multiple locations in the world.. So, the first thing here is that I need to know where people have these issues - is it mainly the US, and if so, where are they located?
What the second issue looks like is a manual route that has gone lost (or malconfigured) and because of that it goes through another route which has terrible optimization. The big blame seems to lie with Telia, I guess their uplink from EU to US.
In my test the first lagspike (nearly 90ms) came from the jump from Paris to New York (if you do a traceroute, the prs is Paris, nyk is New York etc). In my last test from that point it racks up another 37-40ms, but the big issue lies in the jump from EU to US.
Hopefully this is something that ArenaNet can fix soon enough - this is something beyond our control and it is also not that simple - this was caused by a power failure and switches and routers really don't like those, but I hope they can fix it. We just need to get it to their network team ;).
To help me:
-> State if you are in the EU or US, preferably add some more details (state, country)
-> Which problem do you have?
You can download the tool on https://guildwarslegacy.com/gwl-connectivitytester.ps1
Right click on the file and choose Run with PowerShell.
This will open up a console window, press ENTER and type in EU or NA, depending on your location.
This will create a file, gwl-networktest.txt. Please share this file with me - either here or by mail on email@example.com
