We check these services around the clock from our US West region, with the same probes that watch our customers' sites. Nothing here is scraped from someone else's status page — it's what our own checks actually see.
All 48 services we track look fine right now.
One failed check doesn't count. We check most of these services once a minute. A few of the largest providers manage automated traffic from datacenters closely, so we check those every five minutes to stay a polite visitor — the list above marks those. A service is only shown as down here after three failed checks in a row: roughly two minutes of continuous failure at the one-minute cadence, about ten at the five-minute one, before anything on this page turns red. That is the same consecutive-failure rule, at the same default count, that we apply before alerting a customer about their own site. Recording the outage and refreshing this page adds a minute or two on top, so we can be a few minutes behind. We think that's the right trade when the page is making a public claim about someone else's business.
Every one of these checks runs from one region: US West. Each check is made once, by one machine there — nothing in another region re-checks it to confirm. That's deliberate rather than a shortcut. Watching every service from the same vantage point is what makes the response times and uptime figures on these pages comparable to one another, which is most of what they're for.
So “up” here is our view from a US datacenter, not from your sofa. If a service looks fine on this page but not for you, the problem is more likely your network, your DNS, or something specific to your account. It cuts the other way too: a service that blocks or rate-limits traffic from datacenters can look down to us while working perfectly for real visitors, which is why we only list services we have measured as reachable from where we check.
Everything on this page is the ordinary product pointed at well-known services. Want to hear next time, before your customers do? We'll watch it free — 25 monitors, no card — or run a one-off check with the free tools.
