Keep your content online during outages! 🚀 ✅ Serve stale content ✅ Route traffic smartly ✅ Customize with VCL Guide: community.fastly.com/t/vcl-failov... #EdgeComputing #HighAvailability #WebPerformance #DevOps

Oh hey I worked on this! Bonus fun fact: this feature accidentally ended up being really easy to implement due to completely unrelated work normalizing the behavior of VCL function calls. A great example how the right data structures and algorithms can allow your compiler to do more with less.

Proud to share that Fastly was named one of CRN’s Top 25 Hottest Edge Security Companies for 2025 — and our CEO Kip Compton was recognized among leaders shaping the future of edge security. 🔗 www.crn.com/news/securit...
