Website monitoring — beautiful, simple and inexpensive.·updown.io
updown.io is a website and service monitoring tool that periodically checks HTTP(S), TCP(S) and ICMP endpoints and reports downtime, bad responses, degraded performance or SSL certificate problems. It also monitors periodic tasks and cron jobs (pulse monitoring), sends alerts through multiple channels, and provides hosted public status pages with uptime and performance metrics. Checks can run from multiple global locations with dual-stack IPv4/IPv6 support and configurable frequency.
