About Semaphore Status and Outage Monitoring

IsDown has monitored Semaphore continuously since April 2020, tracking this CI/CD & Deployment for 6 years. Over that time, we've documented 227 outages and incidents, averaging 3.3 per month. When Semaphore goes down, incidents typically resolve within 439 minutes based on historical data.

We monitor Semaphore's official status page across 2 components. IsDown interprets Semaphore statuses (operational, degraded performance, partial outage, and major outage) to deliver precise health metrics and filter alerts by the components you actually use.

When Semaphore 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 Semaphore status and receive verified outage alerts through Slack, Teams, PagerDuty, or 20+ other integrations.

How IsDown Monitors Semaphore

IsDown checks Semaphore's status page every few minutes, across all 2 components. We combine official status data with user reports to detect when Semaphore is down, often before the vendor announces it.

When Semaphore 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 Semaphore with IsDown

Track Semaphore incidents and downtimes by severity

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

Get alerted as soon as users report problems with Semaphore

Semaphore 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 Semaphore outages and downtimes

IsDown collects all information from the outages published in Semaphore 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.

Prepare for upcoming Semaphore maintenance events

Semaphore publishes scheduled maintenance events on their status page. IsDown collects all the information for each event and creates a feed that people can follow to ensure they are not surprised by unexpected downtime or problems. We also send the feed in our weekly report, alerting the next maintenances that will take place.

Only get alerted on the Semaphore outages that impact your business

IsDown monitors Semaphore and all their 2 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.

How to check if Semaphore is down?

Why use IsDown to monitor Semaphore instead of the official status page?

Because IsDown is a status page aggregator, which means that we aggregate the status of multiple cloud services. You can monitor Semaphore 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.

How IsDown compares to DownDetector when monitoring Semaphore?

IsDown and DownDetector help users determine if Semaphore 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 instead of just relying on reports from users. The integration allows us to provide more details about Semaphore's Outages, 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.
