So how do they get this data to the GPUs now...? Just run it over the public internet to the datacenter?

- bayindirh 1y agoThey 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.
- nee1r 1y agoWe want to get darkfiber from the datacenter to the office. I love 100Gbps
- dylan604 1y agoI'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.
- geor9e 1y agoDoes San Francisco really still have dark fiber? That 90s bubble sure did overshoot demand.
- madsushi 1y agoDWDM 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.
- dpe82 1y agoI think these days folks say "dark fiber" for any kind of connection you buy. It bothers me too.
- bayindirh 1y agoI 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.
- woooooo 1y agoNoob 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.
- madsushi 1y agoYep, absolutely, often called "wave/wavelength" or "lambda" service, or "lit fiber".
- g413n 1y ago7.5k for zayo 100gig so that's like half of the MRC
- nee1r 1y agoyeah, 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)
