Japanese Internet speed record: what is the truth?
– In June-July 2025, researchers at Japan’s National Institute of Information and Communications Technology (NICT) set a world record: a data transmission rate of 1.02 petabits per second (Pb/s) was achieved—that’s pretty extraordinary.
– This speed is about 3.5 million times faster than the average US Internet, not 3.5 million times faster—to be exact, 3.5 million (which equals 3.5 million)
– This record means that the entire Netflix library can be downloaded in just 1 second—in an instant
– In addition, the official English Wikipedia can be downloaded 10,000 times, multiple 8K videos simultaneously, and even Steam’s entire game library can be downloaded in mere seconds.
**Some important corrections to your statement:**
You wrote “3.5 million times faster”—that’s 3.5 million times—that’s correct.
Said, “The Netflix platform can be downloaded in 1 second”—that’s right, but correct the words a little: “Netflix’s entire library can be downloaded.”
In short:
Japanese researchers have achieved a record internet speed of 1.02 Pb/s.
This speed is about 3.5 million times faster than the average US broadband.
At that speed, the entire Netflix library can be downloaded in one second.
This is a laboratory record—it’s not yet available to ordinary users, but it’s a big sign for future networks (e.g. 6G, international data transmission, AI, and cloud).
