Frequently asked questions

SJ Monitor is an uptime monitoring service that continuously checks websites, APIs, and other endpoints and alerts you when anything goes down, degrades, or changes — so you can find issues before your users do. It also provides status pages and incident tools to communicate reliability.
A monitor is a single target you watch — a URL, host, or port — with its own check settings. SJ Monitor checks it on a schedule and tracks whether it is up or down.
Add an HTTP(s) monitor with your URL, choose a check interval, and we start checking it and alerting you on changes.
From your dashboard, publish a status page and choose which monitors to display. (Status pages are rolling out.)
Websites and APIs (HTTP/S), keywords on a page, ping (ICMP), ports (SMTP/POP3/FTP/custom), cron/heartbeat jobs, SSL certificates, and DNS records.
As often as every 30–60 seconds on paid plans, and every 5 minutes on Free.
Yes — multi-region checking from US East, Central, West, South America and more, requiring agreement from multiple regions before alerting to cut false alarms. (Rolling out.)
By email and SMS the moment we detect an outage, with an all-clear when it recovers. More channels are on the way.
We require several consecutive failures (and, with multi-region, agreement across locations) before declaring DOWN, so a single blip will not page you.
