I'm running a node at 18.104.22.168 . It is stuck at "4 days behind" because right now (for testing reasons) no one is mining.
Unless your technical skill is very high (enough to contribute), you might want to wait another few weeks or so to run the code. Instead I would recommend reading all of the documentation (which is much more stable...most of it hasn't changed at all in over a year). I'd just hate to waste your time.
