Stale-While-Revalidate, Stale-If-Error Available Today
Fastly is excited to announce that as of today, we support stale-while-revalidate and stale-if-error. As a company dedicated to building a better Internet, we work hard to identify and support new standards that move the Web forward. Read on for an explanation of how these Cache-Control extensions make the Web faster and more reliable for browsers and CDNs, and check out documentation of these features.
Building a Fast and Reliable Purging System
At Fastly, we’re always working to make our systems faster and more reliable. One of the more difficult problems we’ve faced is efficient cache invalidation across our global network, or as we call it: Instant Purging. When content changes, our customers issue a purge request, which we then need to deliver to each of our cache servers. The system that handles these purge requests is codenamed Powderhorn.
How Fastly Chooses POP Locations
Build a network that can scale indefinitely, be managed by a small crew of skilled ops and network engineers, and handle current web traffic and the next generation of protocols. Sounds impossible, right? Not true. When planning a major content delivery network, you’d think that it would make sense to put your equipment where the most people are, right? Not always.
New Fastly Logging Features
Over the last few months, we’ve completely overhauled Fastly’s entire logging infrastructure to keep up with our ever-increasing traffic. In addition to improving efficiency and reliability, we added features to make it easier for our customers to integrate with the logging providers they already use.
Introducing Version Diff
Since day one, we’ve baked the concept of versions right into our system at a fundamental level. We want customers to feel empowered to try new things and to be able to quickly roll them back or create a new version if changes are needed. We’ve brought DevOps best practices to our CDN.
Fastly CDN Expands
At Fastly, we’re constantly working to upgrade our network and expand global capacity. Last week, we built up capacity in our Ashburn, New York City, and Los Angeles POPs and brought a new Miami POP online to improve user experience in South and Central America. We also brought a second London POP online and increased the capacity in our existing London and Frankfurt POPs. In addition to our existing POPs in Tokyo and New Zealand, we’ve added new POPs in Singapore and Hong Kong to bring our customers’ content even closer to users in Asia Pacific. These upgrades are already available to current customers.
Build Your Own Network
At Fastly, we’ve been steadily building the world’s most advanced CDN. Since our founding, we’ve expanded the public network to include 17 globally distributed points of presence (POPs) and are now serving more than 20 billion requests per day.
Introducing the Fastly Historical Stats Tool
At Fastly, we’re always looking for ways to help our customers optimize for speed. Today, we’re happy to announce that (by popular request), we’ve made the Fastly control panel even better with a new Historical Stats Tool. We’ve always provided real-time stats, but we wanted to take transparency one step further. Now you can quickly and easily view your entire usage history.
