Early detection is everything
User reports often detect issues before official status pages acknowledge them.
Learn how crowdsourced monitoring
combined with official status pages provides faster outage detection than
relying on either approach alone.

About Substack Status and Outage Monitoring
IsDown has monitored Substack continuously since April 2020, tracking this Email Delivery for 6 years. Over that time, we've documented 192 outages and incidents, averaging 2.8 per month. When Substack goes down, incidents typically resolve within 178 minutes based on historical data.
We monitor Substack's official status page across 5 components. IsDown interprets Substack statuses (operational, degraded performance, partial outage, and major outage) to deliver precise health metrics and filter alerts by the components you actually use.
To check if Substack 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 Substack status and receive verified outage alerts through Slack, Teams, PagerDuty, or 20+ other integrations.
How IsDown Monitors Substack
IsDown checks Substack's status page every few minutes, across all 5 components. We combine official status data with user reports to detect when Substack is down, often before the vendor announces it.
When Substack 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 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 report 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.
