# Welcome to UptimeIO

> Uptime monitoring from three global locations, with confirmed incident detection and instant alerts

## What is UptimeIO?

UptimeIO monitors your websites, APIs, servers and scheduled jobs from three probe locations (Amsterdam, US West and Singapore), confirms failures before raising an incident, and alerts you through the channels you choose.

## Key features

<AccordionGroup>
  <Accordion title="Multi-location confirmation" icon="earth-americas">
    Checks run from Amsterdam, US West and Singapore. An incident opens only after at least three failed checks from different locations, spanning at least two regions, confirm the failure, so a problem at one location does not wake you up.
  </Accordion>

  <Accordion title="Notifications where you work" icon="bell">
    Send alerts to email, Slack, webhooks, Telegram or Pushover. Choose which events each destination receives.
  </Accordion>

  <Accordion title="SSL and domain expiry warnings" icon="shield-check">
    Get warnings before an SSL certificate or domain registration expires, at 30, 15, 7 and 1 days (you choose which).
  </Accordion>

  <Accordion title="Public status pages" icon="browser">
    Publish branded status pages with custom CSS, your own domain (Pro and Scale), subscriber notifications and maintenance announcements.
  </Accordion>

  <Accordion title="REST API" icon="code">
    Manage monitors, groups, incidents and status pages with API keys, and read results programmatically.
