UNPKG has not been actively maintained and has been down since Mar 15, 2025 was down from Mar 15, 2025, 2:00 AM and down for 18 hours (unpkg/unpkg#412). Migrating to jsDelivr means a more stable and reliant service.

It is highly flexible to replace the default unpkg CDN with any other public CDN source for Dash applications. For instance, in the official documentation source code of my fac component library ( https://fac.feffery.tech/ ), I implemented custom modification to switch from unpkg to npmmirror:

Yeah it is possible, but it doesn't hurt to change the default settings so that it would work out of the box.
