My use case is web, remote desktop, video conf, phone (carrier->wifi voice is a transparent feature for me), streaming audio, syncthing.
Only a couple of those things are sensitive to the few seconds per hour that my dish seems to lose connection, and I suspect part of that is poor placement of my dish.
To your question, and TFA's point, though - I've not noticed any change in the frequency or duration of those ephemeral outages, nor any feeling of overall performance degradation.
I might have occasionally noticed evening drops in throughput, but little of my use case is impacted - I put that down to other customers in my cell ramping up their video streaming services that time of day.
The (mean) ~40ms latency has not changed over those two years (as expected).
...what about Starlink's performance over the last 2 years?
