How to check if Calibre is down?

Why use IsDown to monitor Calibre instead of the official status page?

Because IsDown is a status page aggregator, which means that we aggregate the status of multiple cloud services. You can monitor Calibre and all the services that impact your business. Get a dashboard with the health of all services and status updates. Set up notifications via Slack, Datadog, PagerDuty, and more, when a service you monitor has issues or when maintenances are scheduled.

How IsDown compares to DownDetector when monitoring Calibre?

IsDown and DownDetector help users determine if Calibre 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 Calibre'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.

IsDown offers an easy way to monitor Calibre with maximum flexibility

Major Outages Notifications

IsDown monitors Calibre for major outages. A major outage is when Calibre experiences a critical issue that severely affects one or more services/regions. When Calibre 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 Calibre status page for minor outages. A minor outage is when Calibre 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 Calibre 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

Calibre 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 Calibre and all their 20 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

Calibre 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.

We play well with others
