The slow-bond problem is a long-standing question about the minimal strength c of a local defect with global effects on the Kardar-Parisi-Zhang (KPZ) universality class. A consensus on the issue has been delayed due to the discrepancy between various analytical predictions claiming c = 0 and numerical observations claiming c > 0. We revisit the problem via finite-size scaling analyses of the slow-bond effects, which are tested for different boundary conditions through extensive Monte Carlo simulations. Our results provide evidence that the previously reported nonzero c is an artifact of a crossover phenomenon which logarithmically converges to zero as the system size goes to infinity.
