I wonder how big Twitter's infra costs are (capex). Based on the article, they need to build capacity > 2x peak loaf to tolerate one of the DCs failing. But if they instead had 4 and still only tolerated 1 failure, they'd only need capacity > 1.33x peak load.
This doesn't account for the extra overhead associated with extra DCs, but it seems like there's opportunities for major effeciency wins.

- midoridensha 4y agoGo Elon! Shutting down a datacenter will save a lot of energy. I applaud this move. (Though I suppose they could just sell it to some other company.) Now he just needs to shut down the other 2.
