Well, we weren't using Erlang much (and had written very little, if any). And while it's unclear if it's related to Erlang or not, over time our Erlang-based systems have been ripped out of our stack because of their failure to meet our production needs. In particular: Erlang-based systems are fine when they're fine, but undebuggable when they're not. While JavaScript might not be known for its observability, we have been able to advance the state of the art there considerably[1]; at this point there is no question that node.js is much more observable and debuggable in production than Erlang.
