SpaceX says its satellite internet service, Starlink, has achieved a latency under 20 milliseconds, which is on par with ground-based broadband. 

SpaceX included the data in a presentation it sent to the FCC last Friday, which was spotted by Reddit users. The two benchmark tests, conducted using Ookla’s Speedtest.net service, show Starlink achieving a 102 to 103Mbps download rate, 40 to 42Mbps upload rate, and a latency of 18 to 19ms. (Note: Ookla is owned by Ziff Davis, PCMag.com's parent company.)

The presentation is also attached to a letter from SpaceX’s director of satellite policy, David Goldman, which says initial beta tests for Starlink are hitting below 30ms on latency. (For comparison, the average latency for fixed broadband in the US is 25ms, while the rate on mobile networks is at 48ms, according to Speedtest.net.)
