Diablo server issue

Hello, for the past 3 days I’ve been locked out of Diablo multiplayer. I keep getting hit with “The Diablo 3 servers are down.”

I’ve uninstalled/reinstalled the game.
I’ve tried adding a port forward.
I’ve contacted both Microsoft and internet company.
I’ve even factory reset Xbox.
Nothing works.

Blizzard won’t help unless it’s a computer issue. However, I really need assistance. Can someone point me in the right direction. Because I’m super frustrated and would like to get back to playing seasonal content.
