How IsDown compares to DownDetector when monitoring Cisco Duo?

IsDown and DownDetector help users determine if Cisco Duo 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 Cisco Duo'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.

How IsDown works?

  1. IsDown monitors official status pages

    We check the status of the services you're monitoring every few minutes. We aggregate the status and outage information and normalize it. We also collect crowdsourced information to provide early warning signs.

  2. We notify you when there is an outage

    We send you an alert whenever we detect a new incident or an update on the status of the services you're monitoring. You can customize the alerts to your needs to avoid alert fatigue.

  3. Dedicated dashboard and integrations

    Aggregate all the status information in a straightforward dashboard or internal status page. You can also send the information and alerts to your team's communication/monitoring/incident management tools, such as Slack, Datadog, Microsoft Teams, PagerDuty, and more.

IsDown offers an easy way to monitor Cisco Duo with maximum flexibility

Major Outages Notifications

IsDown monitors Phone Support for major outages. A major outage is when Phone Support experiences a critical issue that severely affects one or more services/regions. When Cisco Duo 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.

Minor Outages Notifications

IsDown monitors Cisco Duo status page for minor outages. A minor outage is when Phone Support experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. When a minor outage occurs, IsDown updates its internal status and shares that information on the customer status page. Depending on the customer settings, IsDown will also send notifications.

Outage Details

IsDown collects all information from the outages published in Cisco Duo status page to provide the most accurate information. 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.

Maintenance Feed

Cisco Duo 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.

Component Filtering

IsDown monitors Cisco Duo and all their 528 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.

Early Outage Detection

Cisco Duo and other vendors don't always report outages on time. Our crowdsourced status platform helps you stay ahead of outages. Users report issues and outages, sharing details on what problems they are facing. We use that info to provide early signs of outages. This way, even without an official update, you can stay ahead of possible problems.
