Lots can go wrong: a network request fails, a third-party library breaks, a JavaScript feature is unsupported (assuming JavaScript is even available), a CDN goes down, a user behaves unexpectedly (they double-click a submit button), the list goes on. The more enriched sentence (right) is an enhancement for when the network request succeeds.

The fact that RUM data is used, is an important distinction because some of these metrics (FID excepted) are available in synthetic or “lab-based” web performance tools like Lighthouse that have been the staple of web performance monitoring for many in the past. While you cannot see the historical CrUX values, you can monitor this over time.

A database should accommodate itself to different data distributions, cluster topologies and hardware configurations. Isolated parts of the database can serve read/write requests in case of network partition. To prevent conflicts, a database must sacrifice availability in case of network partitioning and stop all but one partition.
