summary

Netcastle provides CI/CD network testing as a service that automates topology setup, resource checkout, retries and health checks and runs 500K+ tests per day for 11 teams across 68 use-cases. It manages roughly O(1k) test devices, finds pathological bugs that evade statistical sampling, and records 50,000 failed tests (140 days) that stop bugs before production. A centralized lab-as-a-service and heavy engineering uncover microsecond race conditions in drain logic and enable biweekly global switch software updates.
