Know if it’s down before you panic
DownCheck tells you whether a website or service is down for everyone globally, or just for you — using real network probes, not user complaints. No crowd-sourcing. No guessing. Just honest data.
Check a service →Our approach
Active probing — not crowd-sourcing
Most “is it down?” tools work by counting user complaints. When enough people click “I have a problem”, the tool declares an incident. This sounds useful — but it means you’re reading a social signal, not a technical measurement. Reports lag reality by 15–30 minutes. They spike for app updates, viral news, and user confusion.
DownCheck doesn’t count complaints. When you check a service, we immediately send real network requests from Cloudflare’s global edge and report what we actually observe on the network.
User-report tools
- Count user complaint clicks
- Compare to a historical baseline
- 15–30 min lag from outage to detection
- False spikes from app updates & news
- No way to distinguish local vs. global
- Confidence? None shown.
DownCheck
- Sends live HTTP requests to the server
- HTTP probe + 4-resolver DNS consensus
- Results in under 15 seconds
- Data-driven — not sentiment-driven
- Separates global outage from DNS failure
- Confidence score on every result
How it works
Two check methods. One honest verdict.
Every check runs two methods simultaneously — a direct HTTP reachability probe and a 4-resolver DNS consensus — using different protocols. If both agree, we’re highly confident. If they disagree, we tell you that too.
Direct HTTP Probe
A real HTTP GET request sent from Cloudflare Workers. We measure the response code and response time to determine if the server is reachable.
Timeout: 6 seconds
Success: any HTTP response received
DNS Consensus Check
Parallel DNS queries to 4 independent resolvers via DNS-over-HTTPS. DNS failure is often the first sign of a serious outage or domain expiry.

Our philosophy
Honest results. No black box.
We believe you deserve to know exactly how a status check works — not just a coloured dot with no explanation. Every result on DownCheck comes with a confidence score, a breakdown by probe, and an honest explanation of what we can and can’t detect.
Real probes only
Every result is from a live network request made at the time you asked. We never serve cached or stale data as “current status.”
No fake confidence
We cap confidence at 97%, not 100%. No tool checking from a fixed set of locations can be absolutely certain. We say so.
Full transparency
We publish our full methodology — probe types, thresholds, verdict logic, and what we can’t detect.
Privacy first
No account required. No tracking cookies. No user profiling. We collect only what’s needed for the check to work.
Independent
DownCheck is not affiliated with any of the 2,675 services it monitors. Our results are not influenced by commercial relationships.
Always live
56 top services are automatically checked every 5 minutes, around the clock. You see real data the moment you land on a page.
