@evan Do you have the actual answer to this one?

@anca I have *an* answer. It's not possible to determine every single server ever stood up, but I've got records for about 85,000 servers that have communicated with currently live servers. So, it's an OK estimate.

@anca servers that only ever communicated with other servers that have since gone offline wouldn't show up in my data.
