About cdnjs Status and Outage Monitoring
IsDown has monitored cdnjs continuously since March 2021, tracking this Web Hosting & CDN for 5 years. Over that time, we've documented 15 outages and incidents, averaging 0.3 per month.
We monitor cdnjs's official status page across 4 components. IsDown interprets cdnjs statuses (operational, degraded performance, partial outage, and major outage) to deliver precise health metrics and filter alerts by the components you actually use.
When cdnjs is down, IsDown combines official status data with user reports for early detection. Vendors often delay acknowledging problems, so user reports help us alert you before the official announcement.
Engineering and operations teams rely on IsDown to track cdnjs status and receive verified outage alerts through Slack, Teams, PagerDuty, or 20+ other integrations.
How IsDown Monitors cdnjs
IsDown checks cdnjs's status page every few minutes, across all 4 components. We combine official status data with user reports to detect when cdnjs is down, often before the vendor announces it.
When cdnjs status changes, IsDown sends alerts to your preferred channels. Filter by severity to skip noise and focus on outages that affect your business.
What you get when monitoring cdnjs with IsDown
Track cdnjs incidents and downtimes by severity
IsDown checks cdnjs official status page for major/minor outages or downtimes. A major outage is when cdnjs experiences a critical issue that severely affects one or more services/regions. A minor incident is when cdnjs 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 cdnjs outage, we send you an alert and update your dashboard and status page.
Get alerted as soon as users report problems with cdnjs
cdnjs 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.
All the details of cdnjs outages and downtimes
IsDown collects all information from the outages published in cdnjs 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.
Prepare for upcoming cdnjs maintenance events
cdnjs publishes scheduled maintenance events on their status page. IsDown collects all the information for each event and creates a feed that people can follow to ensure they are not surprised by unexpected downtime or problems. We also send the feed in our weekly report, alerting the next maintenances that will take place.
Only get alerted on the cdnjs outages that impact your business
IsDown monitors cdnjs and all their 4 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.
