The WINMTR or Ping test will time out when it hits the Blizzard servers. Those are masked for security reasons. Blizzard can not discuss the internal workings with you. They really don’t have much they can do with individual troubleshooting, esp outside their network.
When Blizzard has an issue, it impacts thousands of people at one time.
Looking at your Tech Support forum post, what little data you have posted looks well within normal range.
Blizz sadly does not own the internet either and really can’t help with issues getting connected unless it is actually at Blizzard and a chunk of players are all down. Other players can help you though and I see an MVP did jump in. You will want to follow through with your thread and give Elocin the info they are asking for in your own thread.
Here is how to do the WINMTR. Let it run for 10 mins or so when you feel you are having issues. That will collect data for that whole 10 mins for every single physical hop your data goes through. It will show packet loss, and latency for every physical hop that is not masked by security protocols.
