Why use IsDown to monitor Substack instead of the official status page?

Because IsDown is a status page aggregator, which means that we aggregate the status of multiple cloud services. You can monitor Substack and all the services that impact your business. Get a dashboard with the health of all services and status updates. Set up notifications via Slack, Datadog, PagerDuty, and more, when a service you monitor has issues or when maintenances are scheduled.

What is a Status Page Aggregator?

A Status Page Aggregator centralizes the status updates from multiple service providers into one dashboard, allowing you to monitor and receive alerts about outages or issues from all your critical services in one place.

How can a Status Page Aggregator benefit our business?

The Status Aggregator brings you the convenience of monitoring all your critical services in one place, eliminating the need to check the status on multiple websites. It ensures timely alerts on service disruptions, helping you quickly address issues and minimize operational impacts.

How IsDown compares to DownDetector?

IsDown and DownDetector help users determine if a service is having problems. The big difference is that IsDown is a status page aggregator. IsDown monitors a service's official status page to give our customers a more reliable source of information. The integration allows us to provide more details about the outage, like incident title, description, updates, and the parts of the affected service. Additionally, users can create internal status pages and set up notifications for all their third-party services.

IsDown offers an easy way to monitor Substack with maximum flexibility

Major Outages Notifications

IsDown monitors Substack for major outages. A major outage is when Substack experiences a critical issue that severely affects one or more services/regions. When Substack marks an incident as a major outage, IsDown updates its internal status, the customer status page and dashboard. Depending on the customer settings, IsDown will also send notifications.

Minor Outages Notifications

IsDown monitors Substack status page for minor outages. A minor outage is when Substack experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. When a minor outage occurs, IsDown updates its internal status and shares that information on the customer status page. Depending on the customer settings, IsDown will also send notifications.

Outage Details

IsDown collects all information from the outages published in Substack status page to provide the most accurate information. 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.

Maintenance Feed

Substack 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.

Component Filtering

IsDown monitors Substack and all their 5 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.

Early Outage Detection

Substack and other vendors don't always report outages on time. Our crowdsourced status platform helps you stay ahead of outages. Users report issues and outages, sharing details on what problems they are facing. We use that info to provide early signs of outages. This way, even without an official update, you can stay ahead of possible problems.

We play well with others
