  We perform a combined fit to global neutrino oscillation data available as of
fall 2016 in the scenario of three-neutrino oscillations and present updated
allowed ranges of the six oscillation parameters. We discuss the differences
arising between the consistent combination of the data samples from accelerator
and reactor experiments compared to partial combinations. We quantify the
confidence in the determination of the less precisely known parameters
$\theta_{23}$, $\delta_\text{CP}$, and the neutrino mass ordering by performing
a Monte Carlo study of the long baseline accelerator and reactor data. We find
that the sensitivity to the mass ordering and the $\theta_{23}$ octant is below
$1\sigma$. Maximal $\theta_{23}$ mixing is allowed at slightly more than 90%
CL. The best fit for the CP violating phase is around $270^\circ$, CP
conservation is allowed at slightly above $1\sigma$, and values of
$\delta_\text{CP} \simeq 90^\circ$ are disfavored at around 99% CL for normal
ordering and higher CL for inverted ordering.
