Episode notes
We Use Open Source Varnish, Not Fastly's Fork
- The team clarified they run the open source Varnish cache, not Fastly's Varnish Plus fork.
- Building on open source was intentional because it fits their values and tooling needs.

- The homepage had a 17.93% cache hit ratio, causing many slow backend requests.
- Low hit rates increase latency and failure surface area, so improving caching was essential.
