What updown.io is

updown.io is a web and API monitoring service from a maker founded in 2012 in Paris, France. It checks HTTP(S), TCP(S) and ICMP endpoints for downtime, poor responses, degraded performance and broken SSL certificates, confirming outages from at least two of 10 monitoring locations. Check intervals range from 15 seconds to one hour, and cron jobs can be monitored for missed completion times. The service also watches TLS/SSL and domain expiration, supports keyword and server monitoring, and provides hosted single-site or multi-site status pages. Alerts can go by email, SMS, Slack, Microsoft Teams, Telegram, webhooks, Statuspage.io and Zapier. REST and webhook APIs are available. Pricing is by checks, with one credit per check; monthly plans start at €5.00 per month, excluding VAT, with no commitment. There is no free plan, but 100,000 trial credits are offered.
