About Customer.io Status and Outage Monitoring
IsDown has monitored Customer.io continuously since April 2020, tracking this Marketing Automation for 6 years. Over that time, we've documented 235 outages and incidents, averaging 3.4 per month. When Customer.io goes down, incidents typically resolve within 58 minutes based on historical data.
We monitor Customer.io's official status page across 15 components organized into 8 groups. IsDown interprets Customer.io 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 Customer.io 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 Customer.io status and receive verified outage alerts through Slack, Teams, PagerDuty, or 20+ other integrations.
How IsDown Monitors Customer.io
IsDown checks Customer.io's status page every few minutes, across all 15 components. We combine official status data with user reports to detect when Customer.io is down, often before the vendor announces it.
When Customer.io 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 Customer.io with IsDown
Track Customer.io incidents and downtimes by severity
IsDown checks Customer.io official status page for major/minor outages or downtimes. A major outage is when Customer.io experiences a critical issue that severely affects one or more services/regions. A minor incident is when Customer.io 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 Customer.io outage, we send you an alert and update your dashboard and status page.
Get alerted as soon as users report problems with Customer.io
Customer.io 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 Customer.io outages and downtimes
IsDown collects all information from the outages published in Customer.io 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 Customer.io maintenance events
Customer.io 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 Customer.io outages that impact your business
IsDown monitors Customer.io and all their 15 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.
