Managed CDN
How Cache Rocket delivers cloud-optimized assets from assets.cacherocket.com.
8 хв чытання
Managed CDN is Cache Rocket’s own asset CDN. When cloud Media jobs finish—image optimization, Critical CSS, or LQIP—the results are stored securely and served from the global edge at https://assets.cacherocket.com.
You do not add assets.cacherocket.com as a custom CDN hostname. The WordPress plugin rewrites eligible URLs automatically when those Media features are enabled and your plan includes Managed CDN.
Two different CDN stories
Managed CDN delivers Cache Rocket-optimized assets. [CDN integrations](/documentation/cdn-integrations) connect *your* Cloudflare, Bunny, Fastly, or KeyCDN account to purge and rewarm HTML/page URLs. Both require the Managed CDN / CDN entitlement on paid plans, but they solve different problems.
What it delivers
- Optimized images — WebP/AVIF (plan-dependent) after cloud image jobs. See Image optimization.
- Critical CSS — generated
critical.cssfiles injected by the WordPress plugin. See Critical CSS. - LQIP placeholders — tiny blurred previews for perceived performance. See LQIP.
Bandwidth and plans
Managed CDN egress is metered as CDN bandwidth (GB / month) on your subscription. Starter, Pro, and Business include increasing monthly allowances. When bandwidth is exhausted, new CDN-backed optimization work hard-stops until the quota resets or you upgrade. See Plans and limits.
| Plan signal | Meaning |
|---|---|
| Managed CDN entitlement | Cloud asset delivery and related CDN features are available. |
| CDN bandwidth GB / month | How much optimized-asset egress you may use this period. |
| CDN purges / day | Daily budget for BYO CDN purge → rewarm actions. |
Cleanup when you disable a feature
In the WordPress plugin, disabling a cloud Media feature deletes that site’s related objects from Cache Rocket CDN storage and attempts an edge purge. That keeps unused assets from lingering after you turn a feature off.
Custom CDN hostnames
Optional custom CDN rewriting (your own hostnames under Advanced) is separate. Do not list assets.cacherocket.com there—it is configured automatically for cloud assets. Use custom hostnames when you already serve static files from Cloudflare, Bunny, or another provider.
Common questions
- Is Managed CDN available on Free?
- No. Managed CDN starts on Starter and above.
- Do I need Bunny or OVH accounts?
- No. Cache Rocket operates the storage and edge for Managed CDN. You only need a Cache Rocket plan with the entitlement.
- Can I use Managed CDN without WordPress?
- Cloud Media jobs today are driven from the WordPress plugin’s Media and Advanced screens. Website/API warming works on any stack without Managed CDN.
