KeyCDN fetches your site from a hostname, not a server address. Where we run your DNS we set it up for you; otherwise you add one record and press Check.
Most CDNs fetch your site straight from our server's address. KeyCDN only fetches from a hostname, so a site on KeyCDN gets its own origin hostname. Only the CDN uses it, and your visitors never see it.
There is nothing to do. When your site moves to KeyCDN we add a record such as o-1a2b3c….example.com to your domain, check that the internet answers it, and build the KeyCDN zone on it.
Open the site's CDN page. The Origin hostname card shows the one record to add:
| Name | Type | Value |
|---|---|---|
| the hostname shown on the card | A | your server's address, shown on the card |
Add it where your domain's DNS is managed, wait a few minutes, then press Check. Once the card says the hostname is in use, KeyCDN can fetch your site.
If you have not added it yet, we give the site a neutral hostname of our own, so a move to KeyCDN still works.
The hostname stays the same and we change the address it points to. If the record is one you added, the move waits and tells you the new address to put in it, so your site is never fetched from a server that is being switched off.
