Regular packet loss since Sunday 7/9/25 17:00
I've noticed over the last week, regular occurrences where websites will fail too load with DNS failures, refresh for a few seconds and it loads fine, similarly "you're not connected" messages in various apps, packet loss indicators when gaming etc.
Since then, I'm seeing regular packets loss on my broadband quality monitor graph, pretty much 24/7, roughly 2-10% loss
The TV breakup seems to have been resolved after the recent work a couple of weeks ago, but internet connection is having issues. This happened a couple of years ago, started out 'small' packet loss, and gradually increased until connection dropped.
