When there are server issues, they report them on the BlizzardCS Twitter. However, there’s been no activity that would cause this super recently. Even though you have good connection bandwidth, and you’re using other services, it’s likely something between you and the servers is not working as intended. Also, streaming services are not a good indication of internet quality, and neither are speedtests. The streams can buffer info so you won’t notice a connection loss, and speedtests only test the max speed ability of your internet.
With any connection issue you want to diagnose, please provide a WinMTR:
WinMTR instructions (click to expand/collapse)
Follow the support documentation for WinMTR. If you’re unable to get into a game for the IP address, then use an IP from the table provided on that page that matches your region. Run the test until you encounter the issue again, or for at least 10 minutes.
Share your results in a reply:
- Click the “Copy Text to clipboard” button after you’ve finished the test per the instructions.
- Paste the text in a reply, then highlight the pasted text and click </> on the post editor.
- Break any links by adding a space before .com, .net, etc.
