About our Mimecast status page integration
Mimecast (Email security and human risk management platform) is a an Email and Security solution that StatusGator has been monitoring since December 2019. Over the past almost 7 years, we have collected data on on more than 585 outages that affected Mimecast users. When Mimecast publishes downtime on their status page, they do so across 120 components and 17 groups using 4 different statuses: up, warn, down, and maintenance which we use to provide granular uptime metrics and notifications.
If you're wondering, "Is Mimecast down?", or need to know its current status, we've got you covered. Our platform tracks every reported outage, performance issue, and maintenance window to ensure you're informed. Whether Mimecast is experiencing a problem now or has recently resolved one, our detailed history keeps you updated.
More than 400 StatusGator users monitor Mimecast to get notified when it's down, is under maintenance, or has an outage. This makes it one of the most popular Email services monitored on our platform. We've sent more than 36,900 notifications to our users about Mimecast incidents, providing transparency and peace of mind. You can get alerts by signing up for a free StatusGator account.
-
Early Warning Signals
If we detect a potential Mimecast outage or other issue before it was reported on the official status page we will send an Early Warning Signal notification to StatusGator subscribers. We can often detect issues before they are officially acknowledged by the provider, giving you a head start on resolving any potential problems.
-
Down notifications
If Mimecast is having system outages or experiencing other critical issues, red down notifications appear on the status page. In most cases, it means that core functions are not working properly, or there is some other serious customer-impacting event underway.
-
Warning notifications
Warn notifications are used when Mimecast is undergoing a non-critical issue like minor service issues, performance degradation, non-core bugs, capacity issues, or problems affecting a small number of users.
-
Maintenance notifications
Mimecast posts separate notifications for planned maintenance work. StatusGator will notify subscribers when Mimecast enters a pre-planned maintenance window, keeping you up to date.
-
Status messages
When Mimecast posts issues on their status page, we collect the main headline message and include that brief information or overview in notifications to StatusGator subscribers.
-
Status details
When Mimecast has outages or other service-impacting events on their status page, we pull down the detailed informational updates and include them in notifications. These messages often include the current details about how the problem is being mitigated, or when the next update will occur.
-
Component status filtering
Because Mimecast has several components, each with their individual statuses, StatusGator can differentiate the status of each component in our notifications to you whenever a particular component is down. This means, you can filter your status page notifications based on the services, regions, or components you utilize. This is an essential feature for complex services with many components or services spread out across many regions.
