About Our Semaphore Status Page Integration

Semaphore is a DevOps, Development, and CI/CD solution that StatusGator has been monitoring since September 2018. Over the past over 5 years, we have collected data on on more than 601 outages that affected Semaphore users. When Semaphore publishes downtime on their status page, they do so across 7 components using 4 different statuses: up, warn, down, and maintenance which we use to provide granular uptime metrics and notifications.

Many StatusGator users monitor Semaphore to get notified when it's down, is under maintenance, or has an outage. We've sent more than 1,600 notifications to our users about Semaphore incidents, providing transparency and peace of mind. You can get alerts by signing up for a free StatusGator account.

If Semaphore 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.

Warn notifications are used when Semaphore 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.

Semaphore posts separate notifications for planned maintenance work. StatusGator will notify subscribers when Semaphore enters a pre-planned maintenance window, keeping you up to date.

Since Semaphore publishes a feed of proactive maintenance events on their status page, StatusGator will collect information about these events. Maintenance events for all your services can be viewed within StatusGator as a unified feed.

When Semaphore posts issues on their status page, we collect the main headline message and include that brief information or overview in notifications to StatusGator subscribers.

When Semaphore 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.

Because Semaphore has several components, each with their individual statuses, StatusGator can differentiate the status of each component in our notifications to you. 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.
