Technically neutrino signalling could make it faster, but those extra milliseconds are not worth it, even for the HFT folks... but thanks to them we have shorter fiber routes across the atlantic at least.

> thanks to them we have shorter fiber routes across the atlantic at least. Can you explain how HFT caused a shorter fiber route across the Atlantic? Is this route open to the non-HFT public? I read Flash Boys and am aware of a custom fiber link between Weehauken, NJ and Chicago, IL, but I thought they are were moving to microwave. I thought there were some HFT links (fiber or microwave) within Europe.

  Microwave is great for latency, but the bandwidth sucks. When you need bandwidth & low latency, you need a more direct fiber link.

  I recall a new transatlantic cable constructed a few years ago being advertised as shaving off a few milliseconds. Trading and cloud providers were mentioned as target customers. I don't know whether they also route public internet traffic.

These should have a lower latency than fibre links although the shortwave link will probably have rather a low data rate.

  And somehow distinguish between the signal and the flood of solar neutrinos.
