I clicked the story wondering if the speed of light has changed since the late 90s.

Apparently not.

It’s still speed of light in a medium, which is not speed of light. Electricity over copper it is 2/3 iirc.

speed of packets over copper I think is actually faster than fibre

[deadbabe]

HFT firms have entire infrastructure that runs very close to the speed of light, beating the competition that runs on antiquated copper.

~200,000km/s is the speed of light in fiber optics. Electromagnetic propagation in copper is more like 99% c.
