Check if any OpenSesame component is down. View the current status of 6 services and regions.
IsDown has monitored OpenSesame continuously since April 2024, tracking this Education Technology for 1 year. Over that time, we've documented 84 outages and incidents, averaging 4.0 per month. When OpenSesame goes down, incidents typically resolve within 283 minutes based on historical data.
We monitor OpenSesame's official status page across 8 components organized into 6 groups. IsDown interprets OpenSesame statuses (operational, degraded performance, partial outage, and major outage) to deliver precise health metrics and filter alerts by the components you actually use.
When OpenSesame 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 OpenSesame status and receive verified outage alerts through Slack, Teams, PagerDuty, or 20+ other integrations.
IsDown checks OpenSesame's status page every few minutes, across all 8 components. We combine official status data with user reports to detect when OpenSesame is down, often before the vendor announces it.
When OpenSesame status changes, IsDown sends alerts to your preferred channels. Filter by severity to skip noise and focus on outages that affect your business.
IsDown checks OpenSesame official status page for major/minor outages or downtimes. A major outage is when OpenSesame experiences a critical issue that severely affects one or more services/regions. A minor incident is when OpenSesame 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 OpenSesame outage, we send you an alert and update your dashboard and status page.
OpenSesame 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.
IsDown collects all information from the outages published in OpenSesame 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.
OpenSesame 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.
IsDown monitors OpenSesame and all their 8 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.
