About Mimecast Status Monitoring

IsDown has maintained continuous monitoring of Mimecast, a Email Delivery solution, since March 2022. Our database contains 125 documented incidents from the past 4 years, giving us deep insight into Mimecast's reliability patterns and typical resolution times. We parse Mimecast's official status page across all 9 components, interpreting statuses like operational and incident to deliver precise uptime metrics and targeted notifications.

When Mimecast experiences issues, you need accurate information fast. IsDown combines official status page data with user-reported issues, giving you early detection when vendors are slow to acknowledge problems, plus verified incident details once they do. You get affected components, severity levels, and real-time resolution updates from both sources.

Engineering and operations teams rely on IsDown to monitor Mimecast and receive verified outage alerts. Get instant notifications through Slack, Teams, PagerDuty, or 20+ other integrations.

How IsDown monitors Mimecast?

IsDown monitors Mimecast health in almost real-time

Every few minutes we check the status page of Mimecast (and 5,420+ other services) for issues. We collect the status and outage information across all 9 Mimecast components. We also monitor user reports alongside official sources. Since vendors often take time to report incidents, monitoring user reports helps us alert you early.

The moment an issue is detected in Mimecast, IsDown sends an alert and updates your status page

Not only will you get notified, but IsDown offers notification filters so you can choose which issues you want to be alerted about. This way you avoid getting all incidents from Mimecast and other services, focusing only on those affecting your business.

One status page to monitor all your external dependencies

What you get when monitoring Mimecast with IsDown

Track Mimecast incidents and downtimes by severity

IsDown checks Mimecast official status page for major/minor outages or downtimes. A major outage is when Mimecast experiences a critical issue that severely affects one or more services/regions. A minor incident 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. The moment we detect a Mimecast outage, we send you an alert and update your dashboard and status page.

Get alerted as soon as users report problems with Mimecast

Mimecast 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.

All the details of Mimecast outages and downtimes

IsDown collects all information from the outages published in Mimecast 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.

Only get alerted on the Mimecast outages 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.
