What concerns me is what control does the ISP actually have over the level of a customers line performance? From my experience, whether it be Afrihost, CISP, Homeconnect, Vox, the actual line performance is pretty similar. The constant being my fibre is delivered via Vumatel (aerial deployment), Do performance issues stem from the ISP or the FNO? I'm saying 20% ISP, 80% FNO based on my personal experiences... I'm most likely way off but perhaps
@websquadza @TheRoDent could chime in.
So the FNO charges the ISP an installation fee and the customer cancels on the back of poor performance, with the FNO being the main influence of said poor performance?
A complicated topic.
Most packet loss issues to local sites/locations are caused by congestion on FNO networks, which results in poor performance, but packet loss affects international performance the most. Most major outages are caused by non-resilient FNO infrastructure, or simply software/hardware upgrades (planned or unplanned).
It takes highlevel resources at ISP's and lots of time and effort to eventually pinpoint a congested GPON, Active Switch, or backhaul and the process can be protracted.
Quality FNO's monitor and upgrade their infrastructure regularly, and some networks just do a better job of it than others, and provide services to the ISP's interconnect at near zero-loss rates.
Vumatel Trenched, and Openserve are basically "rolls royce" networks, and we generally have very few issues with them.
Of course ISP's can also have capacity issues, depending on their business model, and of course, things that happen on the internet at large, can also affect performance, latency and packet loss.
Other than that, the typical issues such as fibre breaks both on the last mile and nationally/internationally can also affect performance at times and cause congestion which affects performance.
What you want, is an ISP that has highlevel resources available when there is a clear problem not related to WiFi, your router or other basic infrastructure, so that you can skip the run-of-the-mill diagnostics.
However, be prepared then to cooperate and provide things like traceroutes, iperf tests, and other contributions in time to help diagnose the issue.
Unfortunately for us (and this happens in a lot of cases) clients tire of the protracted process, and cancel, and move to another ISP, just when the FNO fixes the problem. But it's worth it in the end, as it improves the network for everyone.
