Domains & SSL
Managing Domains
Add custom domains to your CDN deployment with automatic SSL certificate provisioning.
Adding a Domain
Each domain you add to a deployment needs to be configured with:
Domain
The domain or subdomain visitors will use (e.g., cdn.yoursite.com)
Origin URL
Where to fetch content from (e.g., https://your-bucket.s3.amazonaws.com)

DNS Configuration
After adding a domain, you need to configure your DNS to point to Edge CDN.
For subdomains (recommended)
Add a CNAME record:
cdn.yoursite.com. CNAME cdn.edge.network.Root domains (apex domains)
Root domains (e.g., yoursite.com) cannot use CNAME records.
Use your DNS provider's ALIAS or ANAME record type, or consider using Edge DNS which supports this natively.

Domain Status
Domains go through several states during setup:
DNS Status
SSL Status
Automatic SSL Certificates
Edge CDN automatically provisions free SSL certificates for all domains using Let's Encrypt.
Free Certificates
No cost for SSL - included with every domain
Auto-Renewal
Certificates renew automatically before expiration
Fast Issuance
Certificates issued in under 60 seconds
TLS 1.3
Modern encryption with the latest TLS version

Removing a Domain
You can remove a domain from your deployment at any time.
Traffic will stop immediately
When you remove a domain, traffic to that domain will stop being served by Edge CDN. Update your DNS records to point elsewhere before removing.
- Click the trash icon next to the domain you want to remove
- Confirm the removal in the modal
- The domain and its SSL certificate will be removed
