1 The fastest bullets travel more than 2,600 feet per second, or 1,800 mph. 2 Supersonic speed is even slower, 343.2 meters per second, or ≈ 768 mph. 3 Speed of light ≈ 186,000 miles per second. That’s 671,000,000 miles per hour—and the speed of Bluepeak’s fiber internet, give or take a mile or two. But it’s not all about speed. It’s about bandwidth, too. And bandwidth means the amount of data per second that can be carried through your fiber connection.
