Censys Status FAQ

Is Censys down right now?

The verdict at the top of this page comes from the latest poll of the official Censys status feed and refreshes automatically, so you are not looking at a stale cached answer. PulsAPI re-checks a vendor every 60 seconds whenever it is not fully operational, or has changed status in the last 30 minutes, so an incident is always on the fastest cadence. Vendors that are stable and rarely watched are re-checked every 5 to 20 minutes instead.

What should I do if Censys is not working?

Check the component list on this page first to see if your failure matches a known outage. If it does, you can report the issue for other engineers, follow the incident timeline for vendor updates, and run any fallback your app supports until Censys recovers.

How do I check Censys uptime history?

PulsAPI tracks Censys uptime over 30, 60, and 90-day rolling windows. The current 30-day uptime is 99.73%. The 90-day uptime strip on this page is public: no account needed. A free account adds alerts whenever Censys changes state, plus 15 days of incident detail; Pro extends that to 90 days and Business to 13 months.

How fast does PulsAPI detect Censys outages?

PulsAPI reads the official Censys status page. PulsAPI re-checks a vendor every 60 seconds whenever it is not fully operational, or has changed status in the last 30 minutes, so an incident is always on the fastest cadence. Vendors that are stable and rarely watched are re-checked every 5 to 20 minutes instead. Alerts reach Slack, Discord, Microsoft Teams, PagerDuty, or email within seconds of detection.

Does PulsAPI track individual Censys components?

Yes. PulsAPI monitors 32 individual Censys components, so you can see which service or region is affected instead of a generic "service degraded" banner.

Can I get alerts when Censys goes down?

Yes. Create a free account and subscribe to Censys: the free plan covers three services with unlimited email alerts and no monthly notification cap. Paid plans lift the monitor limit entirely (Pro and above do not meter how many vendors you watch) and route the same alerts into Slack, Discord, Microsoft Teams, PagerDuty and webhooks.

How do I report an issue with Censys to the community?

Click "Report an issue" at the top of this page, pick the issue type and severity, and optionally add your region and a short note. Reports are anonymous and help other engineers spot Censys problems early. Official status pages often lag real incidents by 10 to 20 minutes.

Is there a free way to monitor Censys?

Yes. The free plan covers 3 monitored services with unlimited email alerts, permanently, so Censys plus two more costs nothing. Every new account also opens with a 30-day Business trial (unlimited monitors, Slack alerts, SLA reporting) with no credit card.
