How checks work
A simple answer, backed by checks.
We check how websites behave in different places, look for repeated trouble, and turn the latest results into a clear answer.
Background coverage
The research index checks for changes every hour.
Checking the latest background update…
Four simple steps
From a website name to a useful answer
Each step has one job.
- 1 Choose websites Popular sites and background research help us decide what is worth checking.
- 2 Run fresh checks We look at how a site behaves on networks in different countries.
- 3 Compare patterns Repeated, similar failures matter more than one broken connection.
- 4 Explain the result We show what happened, where it happened, and when it was checked.
Reading an answer
Three results you may see
Open a result to see its countries, checks, and updated time.
Blocked
A block was found.
Several checks showed a meaningful access problem. Open the country details to see where and how strong it was.
Not blocked
No block was found.
The available checks did not show a strong blocked pattern.
Unknown
There is not enough data yet.
Too few recent checks or mixed results.
Why results change
Your experience may be different
A country is not one network. Access can change during the day and can differ between home internet, mobile service, workplaces, and cities.
Different providers
One provider may filter a service while another still reaches it normally.
Different places
A local block or outage may affect one region without affecting the whole country.
Different times
Controls can begin, end, or change quickly, so the date of a check matters.
Different coverage
Some places have many recent checks. Others have only a few, which lowers confidence.
Optional technical detail See which evidence matters most +
See how the evidence layers fit together.
Fresh website checks
Recent tests from real networks show whether a site loaded normally or ran into a repeatable problem.
Repeated patterns
The same kind of failure across more than one check matters more than a single broken request.
Outage and network context
A widespread outage or routing problem can look like blocking. This context helps us avoid the wrong conclusion.
Research lists
Background lists help choose websites for fresh checks.
