Siteleaf supports publishing to Rackspace Cloud Files.
Cloud Files is powered by Akamai CDN with over 200 global edge locations around the world.
Published changes can take up to 15 minutes to propogate throughout the Cloud Files CDN.
Custom domains must use a CNAME record (not an A record), this typically means using a subdomain like www.example.com instead of example.com. For more, see using custom domains.
