About IsDown.app and DevOps-Guide

IsDown was built out of frustration at 4 AM. Nuno Tomas, founder and on-call engineer, spent 30 minutes debugging an alert before realising the cloud provider had an outage posted on their status page, but nobody was watching it. That night, he decided there had to be a better way. Today, IsDown...

  • Comprehensive Learning Resource
    The DevOps-Guide repository covers a wide range of DevOps topics including Linux, networking, Docker, Kubernetes, CI/CD, infrastructure as code, and more, making it a one-stop resource for beginners and intermediate learners looking to understand the DevOps landscape.
  • Well-Organized Structure
    The repository is neatly organized into directories and sections by topic (e.g., Docker, Kubernetes, Networking, CI/CD), with clear README files and linked resources, making it easy to navigate and find relevant information quickly.
  • Free and Open Source
    As an open-source GitHub repository, all learning materials, notes, tutorials, and references are freely available to anyone. This makes DevOps education accessible without any cost barrier.
  • Curated External Resources
    The guide includes curated links to high-quality external articles, tutorials, videos, and documentation, saving learners significant time in finding reliable and relevant learning materials across the DevOps ecosystem.
  • Community-Driven Contributions
    Being an open-source project, it benefits from community contributions, which means the content can be updated, corrected, and expanded by practitioners with real-world experience, adding diverse perspectives and keeping the material relevant.

Possible disadvantages

  • Inconsistent Depth of Coverage
    Some topics are covered in great detail with extensive notes and resources, while others have only surface-level content or just a collection of links. This inconsistency can leave learners with gaps in certain areas.
  • Can Become Outdated
    DevOps tools and best practices evolve rapidly. Some sections of the guide may reference older versions of tools or outdated practices, and maintenance of such a broad repository can be challenging to keep everything current.
  • Lack of Hands-On Projects
    While the repository provides theoretical knowledge and notes, it lacks structured hands-on projects or lab exercises that would help learners apply concepts in practical scenarios, which is essential for truly mastering DevOps skills.
  • No Structured Learning Path
    The guide serves more as a reference collection than a structured curriculum. There is no clear progression or recommended learning order, which can be overwhelming for complete beginners who don't know where to start or what to learn next.
  • Limited Original Content
    A significant portion of the repository consists of aggregated links to external resources rather than original, in-depth tutorials or explanations. This means learners are often redirected elsewhere, and external links may break over time.

Questions & Answers

As answered by people managing IsDown.app and DevOps-Guide.

What makes your product unique?

IsDown.app's answer

IsDown monitors official vendor status pages directly, not just crowdsourced reports. This means alerts include real incident context: what broke, which components are affected, and real-time resolution status. Not just "something is down." Combined with crowdsourced early detection signals, IsDown can catch outages before vendors acknowledge them. In January 2026 alone, IsDown detected 101 incidents that vendors never officially reported. Every team monitoring cloud services already has uptime tools that ping their own URLs. IsDown tells you what is happening with the third-party services your stack depends on, before your users feel it.

Why should a person choose your product over its competitors?

IsDown.app's answer

Three reasons:

  1. Coverage: 6,000+ services monitored. If your vendor has a status page, IsDown monitors it.
  2. Speed and context: Alerts go out within seconds of an incident, with full context including affected components, official vendor description, and real-time updates. Not just a notification that something is wrong.
  3. IsDown does not replace your existing tools, it completes them. UptimeRobot and Pingdom tell you your own services are down. IsDown tells you which of your third-party vendors caused it, and exactly what is happening on their end. Setup takes 5 minutes. No engineering required.

How would you describe the primary audience of your product?

IsDown.app's answer

IsDown is built for IT managers, DevOps engineers, and SREs at companies that rely on multiple cloud and SaaS services, which means any team running on cloud infrastructure. The core audiences are DevOps and SRE teams who are on-call and need to know instantly when a third-party service causes an incident; IT managers responsible for vendor oversight and SLA compliance; MSPs and agencies managing cloud infrastructure for multiple clients; and engineering teams who want to stop wasting time debugging problems that turn out to be vendor outages. Customers span SaaS companies, schools, DevOps agencies, and enterprise IT teams across industries.

What's the story behind your product?

IsDown.app's answer

IsDown was built out of frustration at 4 AM. Nuno Tomas, the founder, was on-call when a PagerDuty alert woke him up. After 30 minutes of debugging, he realised the problem was not his code. It was the cloud provider. They had posted an outage on their status page, but nobody on the team was watching it. That night, he decided there had to be a better way. He built the first version of IsDown so his team would never be the last to know about a vendor outage. Founded in 2020, IsDown has since grown to monitor 6,000+ services, perform over 1 billion status checks, detect 520,000+ outages, and send 5.2 million+ notifications. The same problem Nuno solved for his team that night is now solved for IT, DevOps, and engineering teams around the world.

Who are some of the biggest customers of your product?

IsDown.app's answer

IsDown is used by IT, DevOps, and engineering teams across SaaS companies, MSPs, DevOps agencies, schools, and enterprise IT departments.

Which are the primary technologies used for building your product?

IsDown.app's answer

IsDown is a web-based SaaS application. The core product runs on modern cloud infrastructure with multi-region monitoring across US, EU, and Asia to ensure reliable status checks and fast alert delivery worldwide. IsDown integrates directly with Slack, PagerDuty, Datadog, Microsoft Teams, Incident.io, FireHydrant, Grafana, Rootly, Zendesk, and more, connecting alerts to wherever your team already works. For teams using AI assistants, IsDown offers an MCP (Model Context Protocol) Server that allows querying IsDown data directly from AI tools like Claude or ChatGPT.
