Starlink's latency for me is consistently under 25ms, with extremely low jitter. Better than what I can achieve with LTE or VDSL2.
Many of Starlink's customers would otherwise be on VSAT, with 600ms+ RTT to geostationary birds.
By whom?
3ms at the speed of light is 500 miles. Much of what your accessing will be physically further than that anyway.
Also, ever heard of CDNs?
