Just because you’re not having issues connecting to other games or websites, doesn’t mean the issue is Blizzard’s fault or an issue with your modem/router. It could be that your ISP uses a connection path that has problems on the way TO Blizzard. So try some troubleshooting steps, report back on what you’ve tried, and then we can look over your pathping, tracert, and WinMTR results. I’m listening if you want help.
