IsDown is a status page aggregator that monitors if Cogent and all your dependencies are experiencing issues. We combine the status of all the services you dependent and provide a clear view of all your vendors health in one place. We not only monitor official information but also crowdsourced reports. That means that even when Cogent, per example, doesn't report an outage, you will still be notified if other users are experiencing issues.
Every few minutes we go to the status page of Cogent (and 4,522+ other services) and check if they are experiencing issues. We collect the status and outage information of Cogent's 2 components. Also, we not only monitor official sources but also user reports. Sometimes or a lot of times vendors take some time to report an incident, so by monitoring user reports we're able to alert you early.
Not only you will get notified, but IsDown offers notification filters, so you can choose which issues you want to be notified about. This way you avoid getting all the incidents from Cogent and other services.
 
            IsDown checks Cogent official status page for major/minor outages or downtimes. A major outage is when Cogent experiences a critical issue that severely affects one or more services/regions. A minor incident is when Cogent 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 Cogent outage, we send you an alert and update your dashboard and status page.
Cogent 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 Cogent 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.
Our tool was build to be the best way to monitor all your external dependencies in one place. IsDown not only will help you monitor Cogent but also 4,522 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.
Add all your dependencies to your dashboard. IsDown will monitor them in real-time and send you alerts when there is an issue. You can also create a status page for a bird-eye view and share it with your team.
