This is our first post about building out data centers. If you have any questions, we're happy to answer them here :)

How do you deal with drive failures? How often does a Railway team member need to visit a DC? What's it like inside?

Everything is dual redundancy. We run RAID so if a drive fails it's fine; alerting will page oncall which will trigger remote hands onsite, where we have spares for everything in each datacenter

I'm surprised you guys are building new! Tons of Colocation available nearly everywhere in the US, and in the KCMO area, there are even a few dark datacenters available for sale! cool project none-the-less. Bit jealous actually :P

More info on the cost comparison between all the options would be interesting

The requirements end up being pretty specific, based on workloads/power draw/supply chain

So, while we could have bought something off the shelf, that would have been suboptimal from a specs perspective. Plus then we'd have to source supply chain etc.

By owning not just the servers but the whole supply chain, we have redundancy at every layer, from the machine, to the parts on site (for failures), to the supply chain (refilling those spare parts/expanding capacity/etc)

How much additional overhead is there for managing the bare-metal vs cloud? Is it mostly fine after the big effort for initial setup?

Can you share a list of dark datacenters that are for sale. They sound interesting as a business.

We pulled some cost stuff out of the post in final review because we weren't sure it was interesting ... we'll bring it back for a future post
