to be precise : Erlang was modeled from Smalltalk and Prolog, with a bit of Lisp. They did not knew about Hewitt and the Actor model when they created it, and only learned about it later. about the nine nines : it was a british telecom company that claimed it, by extrapolating from a 14 node network during 8 months. I prefer to say that erlang make it easier to reach five nines, then enable you to go to seven nines if you really need it.
