Technically the speed of light in fiber is 2/3c because fiber has a higher index of refraction. Some HFT funds have actually moved away from fiber in some instances because they can pick up a few microseconds by going through the air instead.

Goldman Sachs actually moved to a neutrino beam between London and NYC.
I can't find anything about that online is this a joke or is this actually real
there's nothing about this on Google, and neutrino detectors are definitely not advanced enough for this. was this a joke that went over my head?
Maybe it's a joke about the (anomalous) detection of faster-than-light neutrinos?
