Proactively monitor service performance with SLO alerts

Service level objectives (SLOs) state your team’s goals for maintaining the reliability of your services. Adopting SLOs is an SRE best practice because it can help you ensure that your services perform well and consistently deliver value to users.

What I learned from leading my first incident

A few weeks ago we had a major incident. We were releasing our Practical Guide to Incident Management, and after posting about it online an incident.io employee noticed that the page wasn’t loading. Just to set the scene, I’ve been at incident.io for 3 months and don’t have any experience of incidents in my previous role.

Classifying Severity Levels for Your Organization

Major outages are bound to occur in even the most well-maintained infrastructure and systems. Being able to quickly classify the severity level also allows your on-call team to respond more effectively. Imagine a scenario where your on-call team is getting critical alerts every 15 minutes, user complaints are piling up on social media, and since your platform is inoperative revenue losses are mounting every minute. How do you go about getting your application back on track?

Speedscale Traffic Replay is now v1.0

Nate Lee here, and I’m one of the founders of Speedscale. The founding team’s worked at several observability and testing companies like New Relic, Observe Inc, and iTKO over the last decade. Speedscale traffic replay was borne out of a frustration from reacting to problems (even if they were minor) that could have been prevented with better testing.
