Case Study: Fog Creek Software achieves reduced downtime and reliable, fail‑proof alerting with PagerDuty

Fog Creek Software Better Software Through Better Alerting

Fog Creek Software, the New York–based company behind Trello, FogBugz and Kiln with over 450,000 monthly users, needed to minimize downtime as its SaaS products grew. Its monitoring was split across Pingdom, Nagios and multiple homegrown tools, and alerts were limited to email and SMS—often going unacknowledged and risking outages, customer retention and engineer overload.

Integrating PagerDuty centralized alerting across those systems, added customizable multi‑channel notifications (email, SMS, phone and iOS/Android push) and automated escalations when alerts were missed. The result was fewer missed alerts, reduced downtime, a more resilient failover infrastructure and on‑call engineers who are reliably notified and more confident in incident response.
