Check your client sites from 3 US locations

Paste up to 10 sites. Each one is checked from New York, Dallas and San Francisco by the same workers that run CheckPulse monitoring. You get response time, any location that gets blocked, and days left on the SSL certificate. No signup.

What this checks

  • Uptime from 3 US cities: an HTTP request from New York, Dallas and San Francisco, following redirects, expecting a 200.
  • Response time: the full request time from each location, so you can see where a site is slow.
  • Blocked locations: a site that answers one city and refuses another usually has a firewall or host rule blocking data-center networks.
  • SSL certificate: days until expiry and whether browsers trust it.

Limits

Up to 10 public sites per check and a few checks per hour per visitor. Results are kept for 24 hours at a private link, then deleted. We do not use the sites you enter for anything else.
