How to monitor the status of Substack and all your dependencies?

IsDown is a status page aggregator that monitors if Substack 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 Substack, per example, doesn't report an outage, you will still be notified if other users are experiencing issues.

How IsDown monitors Substack?

IsDown monitors Substack health in almost real-time

Every few minutes we go to the status page of Substack (and 4,522+ other services) and check if they are experiencing issues. We collect the status and outage information of Substack's 5 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.

The moment an issue is detected in Substack, IsDown sends an alert and updates your status page

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 Substack and other services.

One status page to monitor all your external dependencies

What you get when monitoring Substack with IsDown

Track Substack incidents and downtimes by severity

IsDown checks Substack official status page for major/minor outages or downtimes. A major outage is when Substack experiences a critical issue that severely affects one or more services/regions. A minor incident 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. The moment we detect a Substack outage, we send you an alert and update your dashboard and status page.

Get alerted as soon as users reports problems with Substack

Substack 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 Substack outages and downtimes

IsDown collects all information from the outages published in Substack 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 Substack maintenance events

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.

Only get alerted on the Substack outages that impact your business

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.

One platform to monitor all your external dependencies

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 Substack 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.

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.

How IsDown compares to DownDetector when monitoring Substack?

IsDown and DownDetector help users determine if Substack 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 instead of just relying on reports from users. The integration allows us to provide more details about Substack's Outages, 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.
