Original: The AWS Lambda Node.js 20 deadline everyone gets wrong (it's not September 2026)

Short summary

AWS moved the Node.js 20 Lambda block-create and block-update dates to Feb 1 and Mar 3, 2027 — not late 2026 as widely reported. The runtime was already deprecated on Apr 30, 2026, meaning no security patches or support. Multiple runtimes (Node 16/18/20, Python 3.8-3.10, Ruby 3.2, .NET 6) share the same Q1-2027 block dates, creating a synchronized capacity-planning risk across your fleet.

  • •AWS Lambda Node.js 20 block dates moved to Q1 2027, not late 2026
  • •Runtime already deprecated Apr 30 2026 — no security patches, running unpatched
  • •8 runtimes share synchronized block dates — inventory and upgrade now
