What is CloudFront used for?

Why am I being blocked by CloudFront?

Question: I want to access a static URL that I am hosting at GitHub Pages, but I get 404.

5, indicating that CloudFront is getting the request and I don't understand why. This happens intermittently for the past 4-5 days (at different times). To verify, I have tried removing and adding cloudfront to my GitHub repos, but there is no difference between these two cases (404.1 VPS on DigitalOcean, with a LEMP setup. Both in the control panel and when running it from SSH. The files are publicly available on the internet.

The site is hosted on github pages via GitHub Action (see README for setup instructions), and the codebase is generated using goinstall . In case your question is about how caching behaves when you request content that was last accessed a certain amount of time ago (which could be related to your question), the answer is that the cache behaves just like regular RAM: once accessed, you're good until your next cache cycle, so after some time has passed. So, for example, if your content expires in 60 days and you just accessed the file 10 minutes ago, when the content expires, CloudFront will make a network request to get new content and then it will return that data immediately in the next request and from there CloudFront won't make any more network requests until the next cache cycle and won't serve anything. This behavior is described in more detail in the documentation below. If your question is about how CloudFront caches content that was last accessed less than a day ago (something that can happen when it's trying to figure out if to even forward your request to your origin or not), the answer is that CloudFront does not use any special knowledge to know when to cache or not. It uses your request headers to decide this, and also uses an algorithm, described in more detail in the documentation below, which checks if your request is a browser referrer request.

What does it do?

Who should use it?

CloudFront is a web service used by developers to create, manage and deliver digital media content. ? CloudFront lets you deliver content from Amazon Web Services (AWS) so that users in different locations experience the same version of your media or application. It provides the best way to distribute your media or applications so that the right version is delivered to the right users at the right time. When you use CloudFront, you use AWS to set up your own content distribution network, or CDN. AWS then takes care of storing your media on servers in data centers in different parts of the world and delivering it to your users over the Internet, making it easy for you to distribute media content or applications to your end users.

CloudFront is used to: Distribute content and applications to users in different geographic locations, regions or countries, by routing traffic over the Internet through their edge locations. Distribute media assets and applications with static content. This means that the media assets or applications are served through CloudFront, and the source IP address is hidden from users.

This information is available in the About CloudFront section. CloudFront is used by you as a CDN when you use it to distribute your media assets or applications, and for static media. With CloudFront, you no longer have to worry about managing and updating your own servers, and your users can enjoy the benefits of a high-performance CDN without having to pay for additional bandwidth.

If you create a bucket in S3 that contains your media assets or applications, you can associate CloudFront with the bucket using an S3 website, or by creating a URL, which will route users to the content in the bucket in the location where they are located. You can also associate a S3 object with CloudFront so that it delivers that object to the edge location closest to the user. If you choose to use the object with CloudFront, you must pre-select it for the distribution, after which CloudFront will store it in your account for future use. For more information, see the Object association page.

You can set the access control settings for the objects in the bucket, which is useful if you wish to set different permissions on some of your media content. For more information, see Access controls.
