The Forced-Migration Playbook: What Railway's Great Metal Migration Teaches About PaaS Lock-In
Railway moved 1.1M+ users off GCP onto its own hardware in 2025, ending with a 'we migrate them for you' last call. The timeline, the pricing math, and a seven-question exit checklist for anyone picking a PaaS.
Render Renamed Every Compute Plan to 2c-4g Style IDs: An IaC Compatibility Checklist Before You Touch Anything
Render's August 26 rename turned Pro Plus into 4c-8g and promised no action required. The grep commands that inventory every plan reference, the three spellings of each plan, the Workflows flex gotcha, and a six-step checklist that proves an IaC fleet is clean.
