My ISP provides 10mbps download, 768mbps upload. So the asymmetry can be quite extreme even under normal circumstances. Your ISP may simply be trying to minimize your ability to support services without having to upgrade your Internet service plan.
So it's impossible to say if this is or isn't normal unless you tell us what your ISP has promised with your current service plan. We minimally need that as a baseline before proceeding w/ further diagnostics.
