Is 900 Mbps Fast?
Quick answer: 900 Mbps is near-gigabit broadband — the typical speed delivered by full fibre gigabit plans in real-world conditions, and far more than any household needs.
900 Mbps is what speed test users on gigabit (1 Gbps advertised) full fibre plans typically see in real-world testing. The slight gap from 1,000 Mbps is due to network overhead and is entirely normal. In practice, 900 Mbps is the fastest you'll realistically see on a home connection.

Frequently Asked Questions
Why do I get 900 Mbps on a "gigabit" plan?
Gigabit plans are advertised at 1,000 Mbps, but TCP/IP network overhead means real-world throughput is always slightly less. 900–950 Mbps on a wired connection is normal and expected. On Wi-Fi, speeds vary based on your router and distance.
How fast does 900 Mbps download?
At 900 Mbps, a 100 GB file downloads in about 15 minutes. A 50 GB game downloads in roughly 7 minutes.
