Latency

Ask Amazon or your service provider for a latency figure for your connection. Its announcement of the Leo Ultra terminal says the design aims to maximise throughput “while minimizing latency”, and that a direct connection to AWS lowers it for business customers. A low Earth orbit puts it in the same class as Starlink rather than Viasat or HughesNet, but orbital height alone does not establish the latency you will see.

Data and fair use

Check Amazon’s current terms for plans, data allowances, prices and fair-use rules in your area.

Router and dish

Ask your service provider for the terminal or router documentation and its local address.

Known quirks

  • The name changed. Amazon Leo is the former Project Kuiper. Older articles and forum posts use the old name.
  • Business first. In November 2025 Amazon said it was shipping Leo Ultra and Leo Pro terminals to selected enterprise preview customers.

Check with your provider

Ask about these details for your service:

  • Typical latency and how it varies through the day.
  • Home plans, data allowances, prices and what happens after any allowance.
  • Whether customers get a public IPv4 address or share one (CGNAT), and IPv6.
  • The router or terminal’s local address, and whether it has a status page.

With Kilobat

When you have Amazon Leo, Kilobat works on it as on any connection: ping to your router and to the internet in the background, outages with whether your router kept answering, the stutter test, call reports, per-app data and budgets. These measurements are taken from your Mac; Kilobat does not read the Leo terminal itself.
