Case Study: Code.org achieves scalable Hour of Code events reaching millions with PagerDuty

With PagerDuty Code.org Reaches Millions of Young Coders

Code.org is a 60-person non-profit on a mission to give every student access to computer science—best known for its Hour of Code, which reaches students in 180+ countries and tens of millions of participants. Ahead of peak traffic events, their AWS-based stack relied on disparate monitoring tools and a single ops person, leaving no clear triage process or single system of record and making it difficult to delegate incident ownership or scale support.

PagerDuty provided a single system of record and a “dev-of-the-day” distributed on-call model with scheduling, escalation policies, and urgency settings, plus better real-time collaboration with HipChat. This allowed proactive infrastructure work (adding servers and testing changes), faster, more efficient incident resolution, and shared ownership across engineers—giving Code.org the agility and confidence to support its biggest Hour of Code events.
