No, they were actually over the speed of light for a portion of the
signal:
They were also able to create extreme conditions in which the light
signal travelled faster than 300 million meters a second. And even though
this seems to violate all sorts of cherished physical assumptions,

I asked about this article to someone who works on optical properties
of materials. Here's what he says (I don't pretend to understand
everything though):
This is called superluminal propagation, and many groups have shown
it in different media; this one is in fiber. However, this does not

I believe this is referred to as velocity factor.

Perhaps they are referring to being able to vary the speed while it is below

and then speeding it up to 1/5th the speed of light.

To make this operational, will this speed up BGP convergence?
(note that there is a difference between group velocity
and phase velocity. The posters of 300,000 Kilometers Per
Second. It's Not Just a Good Idea, It's the Law! are still
valid).

Man, I knew I should've gotten in on the ground floor in
Well, I would imagine that the faster you can ship the bits,
the faster anything can happen -- including BGP convergence and
botnet attacks (too!). :-)
Yeah, I realize that the possibility to actually speed up
light via the optical transmission systems may be a long
