section.io works with Big Commerce customers to optimise their online stores.
In addition to our standard DNS change if you manage your DNS records through the Big Commerce platform there is an additional configuration required to enable Squixa (Or any other CDN/Optimisation platform).
The Big Commerce DNS portal has a limitation where it does not let you change the www record or the base domain record to point anywhere else. To enable Squixa you will need to move your DNS management to another provider (Such as your registrar or another hosting partner). We can help with this process as needed.
