How do I check if a website is down?

Enter any URL into the isitdown.io checker. We test with 4 independent probe methods (HTTP/1.1 strict TLS, HTTP/2 relaxed TLS, a browser User-Agent GET, and a curl-style HEAD) in parallel and show results within seconds, including HTTP status, response time per method, and a 24-hour history graph.

Is it down for everyone or just me?

isitdown.io checks with 4 independent probe methods (HTTP/1.1, HTTP/2, a browser User-Agent GET, and a curl-style HEAD) simultaneously. If all methods reach the site, the issue is local to you, try flushing DNS, switching networks, or using a VPN. If two or more methods fail, the service is down for everyone.

Yes, checking any site is free with no account required, including status badges, per-method history, and the cloud-cascade tracker. A free account adds 5 saved monitors with email alerts. Optional plans raise the limits and remove ads: Pro at $4.99/month (30 monitors) and Max at $12.99/month (200 monitors).
