Ridiculously laggy today

I did see the notice on Battlenet App that there is an issue with authentication server. Could this be why I was having so many laggy games today? Every single one of my games were at TR of 8 or 10 and I was wondering why because my internet speed was as usual.

tested again today and still getting TR of 8 and 10. Starts with 16 or 24 but quickly drops down to 8 or 10. My internet speed is at 900 mbps download and 40 mbps upload, leading me to think that my internet service provider is not causing the problem. Is anyone outside Korea having this issue?

Thanks for your reply Saieden. I checked the website and I got A+ overall. So I am sure it is not my internet.

Go to dslreports dot com and run the fibre test. If your bufferbloat is anything below A, your isp or local network is the problem.
