You can now view more details on how Vercel's [CDN](https://vercel.com/docs/cdn) globally serves cached content to users as quickly as possible.

In the right-hand panel of the Runtime Logs page, we now list:

- **Cache key**: A unique identifier for a specific version of a cached page
- **Cache tags**: Tags associated with the cached data
- **Revalidation reason**: If a revalidation took place, the reason why the content was being revalidated (time-based, tag-based, or deployment-based)

This is available to all Vercel users at no additional cost. [Try it out](https://vercel.com/d?to=%2F%5Bteam%5D%2F%5Bproject%5D%2Flogs) or learn more about [Runtime Logs](https://vercel.com/docs/logs/runtime).
