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.

Okay, guess I should have read the article first, given the title is Light

Perhaps they are referring to being able to vary the speed while it is
below the speed of light. That is, slowing it down to 1/10th the speed of
light, and then
