Cloudflare Workers

The Cloudflare Workers known-issues page is the strongest example of the genre. It documents specific runtime divergences from Node.js, scheduled-cron drift behavior, and the asset-handling quirks that bit me twice while building this site.

The most operationally useful section is the cron-trigger drift note: Workers cron can fire up to 15 minutes after the scheduled time during peak load, and that single fact has saved me multiple debugging dead-ends. Worth reading before deploying anything that assumes precise scheduling.

The page is maintained by Cloudflare’s developer-docs team and updates as new constraints are documented. Track it.
