Next.js Sitemap Not Updating? Here's the Real Fix If your Next.js sitemap is not updating after you publish new content, you're dealing with a cache-coherence bug that almost nobody writes up. It has an exact symptom, a reproducible root cause, and a one-line fix. This is the guide you'll wish you had the moment you notice /sitemap.xml serving fewer entries than your real site. The symptom: your sitemap lags behind your published content The mismatch is impossible to miss once you look. On our own site, /lab lists 11 published posts, yet /sitemap.xml shows only 7. Same database, same deploy, two different answers. If that gap sounds familiar, you're in the right place. You might have checked your afterChange hook, verified that revalidateTag('posts') fires, and even confirmed that the tagged data refreshes — only to find the sitemap still frozen. That's because the problem lives between two cache layers, not inside the data fetch. Why revalidateTag doesn't fix a stale Next.js sitemap The answer lies in what sitemap.ts actually is. According to the Next.js Metadata Files: sitemap.xml documentation, it's a special Route Handler. And like any Route Handler, Next.js caches its rendered output by default. Here's what happened in our own repository (this bug is documented in a comment at the top of app/(frontend)/sitemap.ts because it cost real indexation time): We read content from Payload using unstable_cache , tagged with the collection slug posts . An afterChange hook called revalidateTag('posts') whenever a post was published. That call did work — it invalidated the inner unstable_cache data entry. But the route's statically-rendered outer XML output was never re-run. The frozen route output kept serving the old XML built from the old data, long after the inner cache was refreshed. Two cache layers. Tag-based revalidation busted the inner one, but the outer route handler cache was never told to re-execute. That's the missing piece. The one-line fix: route-level ISR o

At TechCrunch Disrupt 2026, the Smart Systems Stage will be where energy, infrastructure, and technology collide, covering everything from fusion breakthroughs to the grid strain AI is putting on the entire economy.

Yet another Israeli mass surveillance company : Made by Israeli surveillance company Cognyte, the tech simulates a mobile phone tower, which forces nearby phones to connect to it. That enables cops to keep tabs on any phones in the vicinity ­ whether they’re owned by a suspect in a case or not. Cognyte’s contract with the state of Texas reveals that the simulator, called FalcoNet, can be concealed within the vehicles, hidden in a backpack for on-foot missions or attached to a helicopter. It’s the same technology as the infamous Stingray, one of the original cell-site simulators made by defense giant L3Harris...
