We’ve recently upgraded our hosting infrastructure to take advantage of the fastest CDN on the planet: Fastly. Now, all websites that you host with Webflow on a Custom Domain will enjoy nearly instant page load times. With over 50 data centers and thousands of servers around the world serving your website, we're certain every single one of your users will have a responsive, snappy experience.

Average response times are now only 0.01s (10ms!) compared to 0.05s before. Check out this 3rd party performance test we ran from Loadster:

To get started with Webflow Custom Domains, go to your Dashboard site settings, and add a custom domain. If you added a custom domain prior to 4/20/2015, you must update your A-Records to the new IPs to take advantage of the new hosting infrastructure. You don't have to change any of your CNAME records.
