You do realize that this problem does not only affect people from certain country (Iran) right? there are dozen of popular streamers such as JdotB, Gingi and others having this problem from time to time as well… many people had this problem in 8.3 as OP posted a link to old thread and it got taken care by a caring GM!
If you don’t know how to fix this problem maybe that’s another story, but don’t blame your incompetence on certain people because they’re from a doomed place in world… you’re not making their life any easier than what it already is.

Hello all o/
Im stopping by this thread to let you know that the issue is still being looked into. I highly realise that some of you want more information on what is happening and I can only apologise that I cannot share with you the in-depth analysis of what is going on.
What has been found for many is that the issue seems to stem from a routing problem initially and is compounded later on. By then going to a different shard, the routing can alter and net a better performance. This would also hint at why a VPN works for some because that naturally changes the routing yet you still hit the same Blizzard servers at the end of it.
The issue has not been dismissed despite the radio silence and I can still collect and send on any traceroutes or MTR’s that you guys want to provide. For those that have provided them already, I thank you very much as it has already helped quite a bit in painting the picture of what is happening.
For those that have simply mentioned you have the problem but not provided a connection file in this thread, I can only ask again that you provide this file as the more information we have, the better. Of course this is up to you if you want to provide it however I really do hope that you will if you have not already.
Again I know this doesnt magically fix the issue and I get that alot of you are frustrated by this. I fully understand how frustrating this issue can be and again I assure you, it is something that is being looked into.
