Compare uptime, outage stats, and incident history between Deno and its alternatives.
IsDown has maintained continuous monitoring of Deno, a Serverless Computing solution, since July 2022. Our database contains 53 documented incidents from the past 4 years, giving us deep insight into Deno's reliability patterns and typical resolution times. We parse Deno's official status page across all 11 components, interpreting statuses like operational and incident to deliver precise uptime metrics and targeted notifications.
When Deno experiences issues, you need accurate information fast. IsDown combines official status page data with user-reported issues, giving you early detection when vendors are slow to acknowledge problems, plus verified incident details once they do. You get affected components, severity levels, and real-time resolution updates from both sources.
Engineering and operations teams rely on IsDown to monitor Deno and receive verified outage alerts. Get instant notifications through Slack, Teams, PagerDuty, or 20+ other integrations.
Every few minutes we check the status page of Deno (and 5,420+ other services) for issues. We collect the status and outage information across all 11 Deno components. We also monitor user reports alongside official sources. Since vendors often take time to report incidents, monitoring user reports helps us alert you early.
Not only will you get notified, but IsDown offers notification filters so you can choose which issues you want to be alerted about. This way you avoid getting all incidents from Deno and other services, focusing only on those affecting your business.
IsDown checks Deno official status page for major/minor outages or downtimes. A major outage is when Deno experiences a critical issue that severely affects one or more services/regions. A minor incident is when Deno experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. The moment we detect a Deno outage, we send you an alert and update your dashboard and status page.
Deno and other vendors don't always report outages on time. IsDown collects user reports to provide early detection of outages. This way, even without an official status update, you can stay ahead of possible problems.
IsDown collects all information from the outages published in Deno status page to provide the context of the outage. If available, we gather the title, description, time of the outage, status, and outage updates. Another important piece of information is the affected services/regions which we use to filter the notifications that impact your business.
IsDown monitors Deno and all their 11 components that can be affected by an outage. IsDown allows you to filter the notifications and status page alerts based on the components you care about. For example, you can choose which components or regions affect your business and filter out all other outages. This way you avoid alert fatigue in your team.
Our tool was built to be the best way to monitor all your external dependencies in one place. IsDown not only will help you monitor Deno but also 5,421 other services. Your team and customers will have a clear view of all your dependencies and their status, making it easier to identify and resolve issues.
