My connection to the local Gfiber service is perfect rock solid 0% packet loss.
They host a local speedtest.net node which makes it easy enough to check.
2ms latency, no reported packet loss, 900ish MBPS up/down
If that were my ISP's only job we would be golden...
Sadly, anything PAST that has 15% - 50% packet loss. and\or low transfer rates
This includes Speedtest nodes hosted by ISPS in San Antonio (ATT,. Spectrum etc etc) and anything further afield.
The packet loss is not randomly/evenly distributed, it comes in chunks, with the predictable impact of extremely spiky latency.
The interconnect to ATT specifically seems to be particularly terrible, with transfer rates stuck firmly in the single digits.
Contacting support obviously only results in the typical script reader trying to troubleshoot the perfectly good connection between me and the Gfiber servers, but I pay for connection to the internet not to Gfibers San Antonio servers.
So, I am no network engineer, that's the limit of my internet sleuthing capacity.
How should I go about collecting useful/actionable data to demonstrate the issue, and how can I report it to someone who can do more than ask if i've tried turning it off and on again?
