Squarespace is hosted on our servers, and all of our websites can support significantly high amounts of traffic. As your site gets more and more popular, it will be supported by the same infrastructure that keeps up the many sites that already get millions of pageviews a day.
Although no platform can guarantee 100% uptime, we have a stellar reputation for serving high-traffic sites. For example, our own website is a Squarespace site, and it’s served from the exact same infrastructure we provide to our customers. The massive traffic spike we’ve handled successfully following our Super Bowl ads is a good example of what your site is equipped to handle. For examples of other high-traffic Squarespace sites, visit our Customers page.
Tip: If you're a business needing premium support for a high-traffic site, explore Squarespace Select.
If you’re concerned about handling a high volume of visitors, you might also have questions about security. We use numerous methods to protect our customers, including regular security scans to maintain our PCI DSS compliance, and use of industry-developed and proprietary tools to guard against potential intruders, DDoS attacks, and other vulnerabilities.
Tip: Too much content, especially large image files, can still cause your site to load slowly, particularly on mobile devices. To prevent this, review our tips in My site is loading slowly and Keeping your Squarespace site mobile-friendly.
