Pantheon Launches Global CDN + Automated HTTPS for All Sites

Ari Gold, Product Manager Reading estimate: 3 minutes

Update (April 17, 2023): In addition to our always included Global CDN, Pantheon now offers additional features and customizations with Advanced Global CDN, enabling delivery teams to shape customer experiences at all levels. With Advanced Global CDN, empower teams to independently manage multiple sites without using subdomains, drive growth through iteration, calibrate control over branding, and extend enterprise-grade security.

Pantheon sites are now faster and more secure than ever, thanks to our new, integrated Global CDN. The Content Delivery Network, along with automated HTTPS, is included for all sites, regardless of service level and at no extra cost. We did it by integrating Fastly’s edge cloud platform seamlessly into Pantheon and configured it for advanced caching, optimized for Drupal and WordPress. Next, we added Let’s Encrypt to the mix. The result frees you up from CDN configuration or hassling with manually obtaining or renewing certificates for HTTPS.

As an added bonus, we’ve improved the go-live experience, complete with a new Launch Essentials guide, so it’s easier than ever to take a site live on the platform. If you’ve got an existing Pantheon site and don’t see action required to update your DNS, just open a support chat and you’ll be on your way to a faster and more secure site.

Beat the Speed of Light

Gone down the rabbit hole to optimize your site’s page load time? Seeker of the holy grail of sub-second page loads? Then you know that no matter what you do at the site level, without a CDN, the speed of light is working against you.

Distance from request to origin actually matters, and milliseconds of latency add up with all the round-trips needed to render a full web page. With Pantheon’s legacy infrastructure (out with the old, in with the new!) requests for a site would have to go all the way to our US Datacenter, no matter where in the world the visitor requested the page. Now requests are automatically routed to the closest Point of Presence (POP), with over 40 POPs around the world. Caching content closer to the user—whether in San Jose or Stockholm—means your site can load in less than a second.

Time Is Money, Speed up Your Site!

It’s obvious and almost not worth repeating, but visitors expect sites to load quickly, and there’s a considerable drop off in engagement and revenue the slower a page loads. Google now factors page load time and HTTPS in as ranking signals, part of why HTTPS and a CDN have become mainstream requirements and essential for SEO. So we’re happy to offer this free for all sites on the platform, whether a personal blog or a top 10 Alexa site. All sites get the same, consistent infrastructure. You just add the domain and point the DNS, and we take care of automatically provisioning HTTPS and routing traffic through the new CDN.

Fully Automated HTTPS

We’ve partnered with Let’s Encrypt to automate provisioning certificates. If you’re migrating an existing site to Pantheon, we give you a way to verify domain ownership so you can  pre-provision HTTPS before switching DNS to Pantheon. Or just point DNS to Pantheon’s Global CDN and we’ll always renew the certificates automatically. Never worry about getting another email from a client about an expired certificate. Go ahead and switch DNS to the new Pantheon Global CDN and delete all those pesky calendar reminders to renew certificates.

Top Grade Encryption, SSL Labs A+

SSL Labs is the industry-standard server scanning tool, and you’ll be pleased when you get an A+ rating as we did. Upgrade to the Global CDN for a more secure encrypted connection, configured to require the leading TLS 1.3 protocol (the weak TLS 1.2 ciphers will be deprecated soon). Send the HSTS header as the final step to get an A+ SSL Labs rating. HTTP Strict Transport Security (HSTS) increases your site’s security by helping to prevent protocol downgrade attacks and cookie hijacking. For more details and a comparison with the legacy configuration, see our documentation.

Go Forth and Make Awesome

If you haven’t created a site on Pantheon, give it a try for free. You can also join our upcoming webinar to learn more about Global CDN and automated HTTPS. And as always, if you have specific questions about your existing Pantheon sites, contact support via the dashboard.
