See Semaphore in your Pingoru dashboard

Monitor Semaphore alongside every other service your stack depends on — same alerts, same timeline, same calendar — all in one place.

Every status page, one dashboard

Add Semaphore to your Pingoru monitors and it sits next to AWS, Stripe, GitHub, and every other vendor in your stack — a single dashboard for the live status of every cloud and SaaS provider you depend on. One subscription, one inbox, every incident.

Incident timeline, this provider or all of them

Every Semaphore incident — when it started, when it resolved, which services were affected, how bad it was, how long it lasted — laid out in one feed you can scan in 30 seconds. Filter to just Semaphore or see every provider at once.

Maintenance calendar

Scheduled Semaphore maintenance windows land in the same calendar as every other vendor you depend on — see what's running now, what's coming up, and a calendar view. Plan around your vendors instead of being caught out by them.

Every Semaphore status change, one inbox

Pingoru watches Semaphore's official status page every 5 minutes and delivers incident, resolution, and maintenance events to your email, Slack, Discord, Teams, or webhook.

Only alert on the services you use

Semaphore reports on 7 services. Subscribe to the ones you actually use — everything else stays silent.

Email + Slack + Discord + Teams

Signed webhooks on every plan. Route Semaphore alerts wherever your team already lives — no per-integration billing, no tier-gating the channels that matter.

Maintenance, not surprises

Upcoming Semaphore maintenance windows appear in your maintenance calendar days in advance. Plan deploys and rollouts around them instead of finding out during an incident.

Fine-grained alert control

Per-monitor switches for opened, updated, resolved, and maintenance events. Silence the noisy Semaphore services without silencing the monitor entirely.

Invite your team

Premium includes 10 team seats. Everyone watching Semaphore from the same account, with per-user notification preferences for any monitor.

Get notified on Semaphore status changes

Pingoru watches Semaphore's official status page and sends your team instant alerts when incidents open, change severity, or resolve. Route notifications to email, Slack, Discord, or a webhook — wherever your team already lives.

Frequently asked questions

What is Semaphore's uptime?
Over the last 90 days, Semaphore reported 98.17% uptime on its official status page. That figure is calculated from the public incident timeline at http://status.semaphoreci.com — each minute of degraded, partial-outage, or major-outage status counts against the total. Sign up to Pingoru free to see Semaphore's uptime history rolling forward in real time.
Has Semaphore had outages in 2026?
Yes — Semaphore has had 12 incidents reported on its official status page so far in 2026. The full timeline (start times, durations, components affected) is shown above on this page. Pingoru re-checks the status page every 5 minutes so the count stays current.
When was the last Semaphore outage?
The most recent Semaphore incident was "Delays in job processing", which started on March 12, 2026 and was resolved on March 12, 2026. Pingoru captured this directly from http://status.semaphoreci.com. See the full incident card above for affected components and the update timeline.
How often does Semaphore have outages?
Based on the last 90 days, Semaphore averages 4.0 reported incidents per month on its official status page. Pingoru tracks each one with start time, duration, severity, and affected components — so you can see the pattern at a glance instead of digging through the vendor's archive.
Where is Semaphore's status page?
Semaphore's official status page is http://status.semaphoreci.com. Pingoru polls it every 5 minutes and renders the same data here, alongside every other cloud or SaaS provider you depend on — so you can spot multi-vendor incidents (e.g. AWS + Stripe + Cloudflare degrading at the same minute) without flipping between tabs.
Is Semaphore down right now?
Semaphore is up. Pingoru checks the official status page every 5 minutes and flips this headline the moment Semaphore reports a change. Current status is based on 7 tracked services.
How does Pingoru know if Semaphore is down?
We read http://status.semaphoreci.com directly, using Semaphore's own status page. If the vendor reports an incident, you see it within one check cycle — not after someone manually marks the page as down.
Where can I get notified when Semaphore has an outage?
Create a free Pingoru account and add Semaphore as a monitor. You can filter to specific services, pick severity thresholds, and route alerts via email, Slack, Discord, or a webhook.
Semaphore's status page says the service is up, but I'm having issues — what's wrong?
Three common reasons: • A real Semaphore incident that hasn't been acknowledged on their public status page yet — vendor status pages are updated manually and typically lag the first customer reports by 10–30 minutes. • A regional or account-scoped issue affecting a subset of customers — these rarely trigger a global status-page change. • A local problem: ISP / DNS / your own software. Try reproducing from a mobile data connection and from a different network to isolate. If you suspect a real Semaphore issue that isn't reflected yet, contact their support to escalate. Subscribing here means you get the alert the moment they do post an update.
Where does Pingoru get the official Semaphore status?
We use Semaphore's own status page at http://status.semaphoreci.com. Nothing is read in a way the vendor hasn't explicitly made public — we use the same data their own dashboard uses. So our data is as accurate as what you'd see loading the status page yourself, but rolled into one dashboard alongside every other service you depend on.
What does "Up" mean?
All tracked Semaphore components are reporting operational. No incidents are currently affecting service.

Stop finding out from your users.

We watch Semaphore's official status page every 5 minutes. The moment they report an incident, you get an email — often before the outage is widely noticed.
