About Mimecast Status and Outage Monitoring
IsDown has monitored Mimecast continuously since March 2022, tracking this Email Delivery for 4 years. Over that time, we've documented 140 outages and incidents, averaging 2.9 per month.
We monitor Mimecast's official status page across 9 components. IsDown interprets Mimecast statuses (operational and incident) to deliver precise health metrics and filter alerts by the components you actually use.
To check if Mimecast 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 Mimecast status and receive verified outage alerts through Slack, Teams, PagerDuty, or 20+ other integrations.
How IsDown Monitors Mimecast
IsDown checks Mimecast's status page every few minutes, across all 9 components. We combine official status data with user reports to detect when Mimecast is down, often before the vendor announces it.
When Mimecast status changes, IsDown sends alerts to your preferred channels. Filter by severity to skip noise and focus on outages that affect your business.
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.
