Monitoring LineOne since May 2025
Tracking 12 LineOne services and regions
0 incidents in 2025
IsDown is a status page aggregator that monitors if LineOne 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 LineOne, 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 LineOne (and 4,522+ other services) and check if they are experiencing issues. We collect the status and outage information of LineOne's 12 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 LineOne and other services.
 
            IsDown checks LineOne official status page for major/minor outages or downtimes. A major outage is when LineOne experiences a critical issue that severely affects one or more services/regions. A minor incident is when LineOne 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 LineOne outage, we send you an alert and update your dashboard and status page.
LineOne 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 LineOne 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 LineOne and all their 12 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 build to be the best way to monitor all your external dependencies in one place. IsDown not only will help you monitor LineOne 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.

Additionally, users can create internal status pages and set up notifications for all their third-party services.
