If you use brave browser it usually is able to point you to corresponding web archive pages when SO is down. Nice to have it directly integrated into the browser

So what is their stack, or where can I find more about it? A totally custom webserver? Someone commented to this effect the yesterday [1], but I couldn't find much in the way of a good writeup, except this answer from 2009 [2]. 1 https://news.ycombinator.com/item?id=32321726 2 https://stackoverflow.com/questions/676326/how-does-stackove...

I remember hearing that they are a .NET stack with C# and SQL Server.

The only reason I know that is because I was working at a company and discussing the issues the company was running into scaling SQL Server and Stack Overflow was used as a counter example of SQL Server scalability. It lead into a long discussion of caching on high read workloads.

I'll never touch SQL Server again if I can help it.

Awesome! Let us know when we can start using your new open source service, it must be mirrored and need it right now.

Stackoverflow's data is cc-by-sa 4.0 licensed and can be found here: https://archive.org/details/stackexchange

So nothing is stopping anyone to spin-up multiple instances.

builtwith.com gives a lot of information, although the results page comes back with a "Misleading Technology Profile Warning".

Not specifically stackoverflow, but here is an answer on stackexchange [1] listing many of the parts that make up their stack.

I'm assuming stackoverflow runs as a part of all this, and not separately.

Scott Hanselman had an interview with the Stack Overflow Director of Engineering just a few weeks ago. They cover some high-level details there [0]. As I understand it's an .NET Core monolith with a very-large (~1.5 TB RAM) SQL Server backend.

I think that's already the case. Whenever I look up a technical issue, the first result is usually from SO; the next results are usually from websites that copied that first SO page
