On June 28th, 2017, we marked four years of performing “Failure Fridays” at PagerDuty. As a quick recap, Failure Fridays are a practice we conduct weekly at PagerDuty to inject faults into our production environment in a controlled way, and without customer impact. They’ve been foundational for us to verify our resiliency engineering efforts. Over […]

You like sleep and weekends. Customers hate losing access to your system due to maintenance. PagerDuty operations engineer Doug Barth has the solution: Ditch scheduled maintenance altogether. That sounds like a bold proposition. But as Doug explained at DevOps Days Chicago, it actually makes a lot of sense. Scheduled maintenance tends to take place late […]

How we drink our own champagne (and do monitoring at PagerDuty) We deliver over 4 Million alerts each month, and companies count on us to let them know when they have outages. So, who watches the watchmen? Arup Chakrabarti, PagerDuty’s engineering manager, spoke about how we monitor our own systems at DevOps Days Chicago earlier […]
When something goes wrong, getting to the ‘what’ without worrying about the ‘who’ is critical for understanding failures. Two engineering managers share their strategies for running blameless post mortems. Failure is inevitable in complex systems. While it’s tempting to find a single person to blame, according to Sidney Dekker, these failures are usually the results […]

PagerDuty engineers are obsessed with reliability. Letting down customers when they’ve been paged is the worst. With that in mind, we’re always designing and thinking of ways to maintain and build systems that maximize resiliency — including our mobile apps. After the release of redesigned mobile applications last October, we’ve been shipping new features and […]

Reliability is important to us. We even inject failure into our systems every Friday to prove it. But when it comes to sending alerts, reliability goes beyonds writing flawless code. We rely on several third-party carriers to deliver alerts to our customers. If an SMS isn’t delivered, you aren’t notified of an outage. We can’t stick […]
