Hi, I agree, I've been having issues for tonight at least. We're in Paralowie on Cable. Pinging doesn't seem to be an issue. Speed Test also seems to show the ping is 9ms and speeds are great. However, that being said, loading the speed test, browsing in general is woeful.
I wasn't sure if it's an issue locally as we have roadworks being done around 1km away. I'm guessing based on your post that's not the cause of my problems.
