AI Weekly Malaysia

Netlify rebuilt its Edge Functions platform, moving off a hosted V8-isolate execution service to Firecracker MicroVMs running inside its own edge network, in work done with Unikraft. Warm invocation p50 latency dropped from 25–40ms to ~5–6ms, p99 improved 47.4%, edge function log delivery got 5x faster, and Netlify reports 99.998% availability across roughly a billion Edge Functions per day. Cold invocations still occur on about 1.2% of requests (~9ms average to fetch images), and the authoring model is unchanged: URL imports, npm packages, Node built-ins, netlify.toml declarations, and local dev all work as before.

Why: If you run latency-sensitive logic on Netlify Edge Functions, this is a free ~5x median latency win with no code migration — worth re-measuring anything you previously pushed back to an origin server or a regional function because the edge felt too slow. Treat the numbers as vendor self-reported with no third-party replication, and note that cold invocations are still Netlify's own 1.2% figure, not something you can verify from your dashboard. There is no Malaysia or SEA angle in this post.
