After a successful Beta phase, Pantheon's next-generation Global CDN (GCDN) is now generally available. Built on Cloudflare, the new GCDN delivers built-in bot protection, expanded site eligibility, and the same self-serve migration experience customers have been using in the Beta — now production-ready for the majority of sites on the platform.
What's included
- Built-in bot protection — Incoming traffic is automatically scored, with managed challenges issued to suspicious requests and verified bots (such as search engine crawlers) allowed through.
- Multizone Failover support — Sites with Multizone Failover enabled can migrate to GCDN and continue to benefit from automated regional failover.
- Custom Certificates support — Sites using customer-provided TLS certificates are now supported on GCDN. Migration for these sites is owned by our Professional Services team and coordinated through support — open a support ticket to get started.
- Platform vanity domain support — Organization-owned vanity hostnames (e.g.,
live-mysite.example-agency.com) are fully supported. Migration for these sites is owned by our Professional Services team and coordinated through support — open a support ticket to get started.
Action Required
Eligible sites will display a GCDN banner in the Pantheon dashboard. To migrate:
- Locate the GCDN banner on an eligible site.
- Click it and complete the guided process.
- Point your DNS records to the new GCDN infrastructure.
Domain verification supports DNS-01 TXT record validation, requiring TXT records added at your DNS provider.
Eligibility
GCDN is available to all sites on the platform except those currently using Advanced Global CDN (AGCDN). AGCDN customers will be migrated in a future phase — no action is required from them at this time.
