IsDown pulls data from Mimecast's status page every few minutes and collects user-reported issues. Refresh the page to see if there are any updates.
This chart displays the number of user-reported issues over the past 24 hours, grouped into 20-minute intervals. It's normal to see occasional reports, which may be due to individual user issues rather than a broader problem. We only consider an issue widespread if there are multiple reports within a short timeframe.

Because IsDown is a status page aggregator, which means that we aggregate the status of multiple cloud services. You can monitor Mimecast 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.
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.
IsDown offers an easy way to monitor Mimecast with maximum flexibility
IsDown monitors Mimecast for major outages. A major outage is when Mimecast experiences a critical issue that severely affects one or more services/regions. When Mimecast 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.
IsDown monitors Mimecast status page for minor outages. A minor outage is when Mimecast 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.
IsDown collects all information from the outages published in Mimecast 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.
IsDown monitors Mimecast and all their 9 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.
Mimecast 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.
