What is Hosting Bandwidth?

Hosting Bandwidth is the total amount of data transferred from your hosted Site to your visitors' internet browsers. Every time someone loads a page, CloudCannon serves the HTML, images, and other files that make up that webpage, and the size of everything served counts toward your Hosting Bandwidth.

How much bandwidth your Site uses depends on how many people visit it and how large your pages are. Media-heavy pages, large images, and file downloads use it fastest, while lightweight, text-based pages use the least. CloudCannon serves your Site through a Content Delivery Network (CDN), so returning visitors are often served cached copies, but all data served still counts toward your usage.

Each Subscription Plan includes a set amount of Hosting Bandwidth each month. For the amount included in each Subscription Plan, see the CloudCannon pricing page.

How much Hosting Bandwidth do I need?

The amount of data each webpage needs is measured in megabytes (MB), and mostly depends on how many image or media files are on the page and how optimized your website is. For example, a 4 MB webpage with several images or media files will serve around 25,000 page views with 100 GB of Hosting Bandwidth. Most optimized webpages are smaller than this, so a 100 GB bundle will go further.

What happens if I reach my bandwidth limit?#

If your Organization needs more bandwidth than your Subscription Plan includes, you can enable Overages. CloudCannon then serves traffic beyond your included amount and bills you for the extra in fixed-size bundles.

If Overages are disabled and you reach your limit, your Sites are taken offline for the remainder of the month or until you enable Overages. Visitors to your Custom Domains or Testing Domains will see an error message. For more information, please read our documentation on what Add-Ons and Overages are.

A screenshot of the unavailable page a visitor sees shows the heading This website is currently unavailable and a message that the website has reached its hosting bandwidth limit, asking them to contact the site's owner.

Track your Hosting Bandwidth#

You can monitor your Hosting Bandwidth on the Usage tab, which shows your cumulative usage over the current month alongside your included limit. Checking it regularly helps you see when you are approaching your limit and decide whether to enable Overages, add capacity, or change your Subscription Plan.

A screenshot of the Usage tab on the Site Dashboard shows the Bandwidth and Build Time graphs and tables.

You can find usage in two places: the Usage tab on your Site Dashboard shows a single Site, and the Usage tab on your Organization Home page shows every Site in your Organization.
