When Klaviyo 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.

Klaviyo publishes scheduled maintenance events on their status page.

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.
Klaviyo and other vendors don't always report outages on time. Our crowdsourced status platform helps you stay ahead of outages.

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.
