Check a website from 3 locations

Is a site down everywhere, or only in some parts of the world? Check it from three regions at once and compare status and response times.

Good to know

Why would a site be down in only one region?: A CDN or hosting location having trouble, a network route problem between countries, DNS that points different regions to different servers, or a firewall that blocks some countries.
Why are response times so different?: Distance. A server in the US answers visitors in Singapore more slowly than visitors in California, because every round trip crosses an ocean. A CDN brings content closer to each region.
Watch it from every region: Spot Downtime confirms every failure from California, Amsterdam and Singapore before alerting you, so a problem near one checker never wakes you up.

Checking by hand only tells you about right now. Spot Downtime checks your sites around the clock and alerts you by email, Slack or Discord.
