  We evaluate the thermodynamic quantities of Yang-Mills theory using the
Gribov quantization, which deals with nonperturbative resummation. The magnetic
scale is automatically incorporated into the framework and we find it efficient
to stabilize the perturbative expansion of the free energy. In the temperature
range $T=T_c \sim 2\,T_c$ the major uncertainty in our results comes from the
nonperturbative running coupling that is adopted from the lattice simulation,
while the convergence above $2\,T_c$ is impressively robust. We also present
the corresponding interaction measure (i.e., trace anomaly) up to close to
$T_c$.
