And you thought your 5G was fast.

The Energy Sciences Network (ESnet) is the fastest Internet network in the world, and it recently got even faster. ESnet6 transmits data at a blistering 46 Terabits per second (Tbps). That’s 46 million megabits per second (Mbps), compared to the few hundred Mbps that most people get at home.

The network was created in 1986 to connect the U.S. Department of Energy’s labs so scientists could share large quantities of data. It has since grown to 15,000 miles of fiber-optic cable that spans the whole country. Last year alone, a total of 1.1 exabytes of data traveled along it. Scientists use it to send data between teams, instruments and facilities to help them research data-intensive things like climate modeling, genomic studies, telescope observations, physics experiments and quantum information.
