Instead of having each individual user wondering if their internet is playing up, could you please use the client to notify users that you’re aware of server issues? Or Twitter, or Sticky a thread. Anything.
This is the response from one of the Tech Supports on NA (called Nicole…)
“Usually their ticket queues and forums are flooded when it’s a server issue (haven’t spotted any floods of posts here or on EU forum), so it’s hard to be sure. Plus, only the one EU WinMTR is showing issues, not both. I’m sure if there is a server issue we’ll see a tweet from Blizzard, or perhaps they’ll share some info in the EU forum.”
