In keeping with the recommendations of PCI DSS, we no longer support TLS 1.0 for customer sites. Older browsers and mobile devices that do not support TLS 1.1 and 1.2 will likely experience problems and security vulnerabilities. If you need to continue support for TLS 1.0, you can do so with Cloudflare. For details, see Cloudflare's documentation.
