This recent Roscosmos tweet (found in CNET's See astronaut's wild view of a discarded ISS module burning up) says:
The non-combustible structural elements of the #ProgressMS16 cargo ship and the #Pirs module fell in a non-navigable area of the Pacific Ocean.
Thank you for your work, Progress and Pirs!
Question: Into what non-navigable Pacific Ocean area did structural elements of the Progress MS16 cargo ship & Pirs module fall? Are there maps of these areas?
I'm curious if there are officially designated "non-navigable" areas in the Pacific and other oceans, and if mission designers know about them and aim for them, and if so, into which one of them this mission aimed.

So long DC1! After almost twenty years of service, instead of getting a medal First place medal, one of the @Space_Station's oldest @roscosmos modules got a little trip through the atmosphere. Shooting star #MissionAlpha https://flic.kr/p/2mdysX9
