FYI, this is NOT the cable Facebook is planning to build, this is the dream cable of a submarine cable… enthusiast? From LinkedIn: “To be clear, this is not Meta's plan or map. This is Ver "T" and T stands for Tagare. It's what I think is going to happen to this cable if I was designing it. This is my wish list.”
I’ve heard stories from people who have worked at Hanford, and it seems like a lot of that money is being squandered. Excess caution, basically everything is radioactive waste, and just overall wasteful spending for decades.
Pretty wild for a single fiber, but super involved, using 5 different doping type amps. Current systems use just EDFAs (Erbium). These guys used Erbium, Thallium, Bismuth, and others.
I updated my map for AWS in Northern Virginia -- came up with 74 buildings (another source says 76, so i'll call it directionally correct). If I scale my sq ft by ~5% to account for missing buildings, we get 11,500,000sq ft in the northern virginia area for AWS.
Google certainly has more compute density than Amazon, the numbers I was able to find from the local power company was 250MW at Council Bluffs back in 2015 or so.
Amazon builds out 32MW shells, and the most utilized as of 5 or 6 years ago was 24MW or so, with most being much less than that.
To date, facebook has built, or is building, 47,100,000 sq ft of space, totaling nearly $24bn in investment. Based on available/disclosed power numbers and extrapolating per sqft, I get something like 4770MW.
Last I updated my spreadsheet in 2019, Google had $17bn in investments across their datacenters, totaling 13,260,000 sq ft of datacenter space. Additional buildings have been built since then, but not to the scale of an additional 30mil sq ft.
Amazon operates ~80 datacenter buildings in Northern Virginia, each ~200,000 sq ft -- about 16,000,000sq ft total in that region, the other regions are much much smaller, perhaps another 4 mil sq ft. When I'm bored I'll go update all my maps and spreadsheets.
Went from codex/claude code -> opencode -> pi -> oh-my-pi
