About UptimeObserver

UptimeObserver watches websites and infrastructure from multiple regions. Monitor types include HTTPS website checks, SSL certificate expiry, domain name expiry, DNS changes, port checks and ICMP ping, with checks as often as every 30 seconds on higher plans so problems surface in under a minute. Alerts go out by email, Telegram, Pushover, Slack, Discord and webhooks when a site goes down or a certificate nears expiry.

Status pages can use custom domains, and the site offers integrations and a set of free tools such as DNS record lookups, an SPF checker, an SSL certificate checker, a disposable email checker, a domain expiry checker, a downtime cost calculator and a cron expression helper. The interface is available in English and French.
