You might want to pass along this to whomever can look into it further:
From what I have been observing for the past month, after having multiple tests done here:
-For everyone having connection issues of various types: UPDATE 8-7-23
My observations are somewhat two fold. First off, the obvious. For some people, it seems the traffic generated playing Diablo IV is being either blocked or de-prioritized by some ISPs as it travels along their network. The user can do other tasks, play other Blizzard games, but for some reason only Diablo IV is affected.
This has been posted about, complained about, and generally shown to be a prevalent case across the globe, as it persists for multiple countries. There are hundreds of posts across LOTS of threads about this. Granted not all examples are going to be equal, but there are too many to ignore.
Second, the fact that there are a few setups where the game actually crashes home hardware. And continues to crash it, even when checked for firmware updates, replaced by the ISP, etc. And ONLY when Diablo IV is played on that hardware.
So while I can appreciate that Blizzard feels its not their problem, it still might be something they are doing with their traffic that is potentially causing some ISPs and some hardware to choke on it. Therefore, this needs SERIOUS attention and continued following up as to what Blizzard intends to do from their end to help mitigate the issue.
Us as players can only do so much. If we are held hostage to the type of equipment we have to use, or the ISP we have to use, why should we be punished for that? Especially in the cases where ONLY Diablo IV is affected?
You can see why that this would garner a lot of angry players. Please take this matter more seriously than your team has been showing us as a player base.
Thanks,
