yeah, exactly! we have a 100G uplink, and then we use nginx secure links that we then just curl from the machines using HTTP. (funnily HTTPS adds overhead so we just pre-sign URLs)

7.5k for zayo 100gig so that's like half of the MRC

They can rent a dark fiber for themselves for that distance, and it'll be cheap.

However, as they noted they use 100gbps capacity from their ISP.

We want to get darkfiber from the datacenter to the office. I love 100Gbps

I'm now envisioning a poster with a strand of fiber wearing aviators with large font size Impact font reading Dark Fiber with literal laser beams coming out of the eyes.

Does San Francisco really still have dark fiber? That 90s bubble sure did overshoot demand.

DWDM tech improvements have outpaced nearly every other form of technology growth, so the same single pair of fiber that used to carry 10 Mbps can now carry 20 Tbps, which is a 2,000,000x multiplier. The same somewhat-fixed supply of fiber can go a very long way today, so the price pressure for access is less than you might expect.

I think these days folks say "dark fiber" for any kind of connection you buy. It bothers me too.

I meant a “single mode, non terminated fiber optic cable from point to point”. In other words, your own cable without any other traffic on it.

A shared one will be metro Ethernet in my parlance.

Noob question, is there an in-between where people sell spectrum bands on a shared fiber without going up to L2? Or is that just too complex compared to using off the shelf ethernet and sharing that.

Yep, absolutely, often called "wave/wavelength" or "lambda" service, or "lit fiber".
