Report #64582

[bug\_fix] Fetch data appears stale in production \(default caching behavior\)

Explicitly set cache: 'no-store' or next: \{ revalidate: 0 \} in fetch options to disable caching, or use unstable\_noStore\(\) from next/cache. For dynamic data, configure revalidation intervals appropriately.

Journey Context:
Developer writes const data = await fetch\('https://api.example.com/data'\) in a Server Component. In local development, fresh data appears on every refresh. After deploying to Vercel production, they update the API data but the Next.js site shows the old data for hours. They check Network tab and see no new requests being made from the server. They try hard refresh, clearing CDN cache, but the data persists. They search and find Next.js docs stating that fetch defaults to force-cache in App Router. They realize the data is cached indefinitely across requests and builds. They add cache: 'no-store' to the fetch call, redeploy, and see fresh data immediately.
