Down for Just Me or Everyone
A modern is-it-down website checker that probes website statuses from two geographical locations (Singapore and Boston) to avoid false positives caused by datacenter IPs being blocked, letting it distinguish 'unreachable from Asia' from 'down for everyone'. It covers 634 curated sites, uses no cookies, analytics, or ads (pageviews are counted from the proxy access log), and offers a free API and an MCP server.
What it addresses
Existing checkers are prone to false positives because they show sites like irs.gov, ssa.gov, and ups.com as down when they are merely blocking datacenter IPs from certain regions; a second probe in Boston fixes this.

“I am working on a modern is-it-down website checker that checks website statuses from two geographical locations. This was the interesting part for me, to get them working together to avoid false positives.”
