Thank you for this rabbit hole. Today I learned a lot about modulation, frequencies, and how DSL works :)

In the end, the most surprising snippet of knowledge for me was that Erlang (that Amazon S3 is built in) was invented by Ericsson for live patching ISDN phone routing systems without dropping any ongoing call.

I do not believe S3 is written in Erlang... do you have a source for this?

SimpleDB is; maybe they confused them.

Sorry, yes. They called it Simple Data Service = SDS in the article and then I incorrectly assumed that it's what we now know as S3.
