Bug reports, suggestions and privacy requests are all welcome at the address below.

Including the page address, your browser, and the exact input you used makes it much quicker to look into.

Every check reflects the answer received at that moment. A recent DNS change may still be propagating, and some hosts block requests by region.

If a result stays wrong, send the domain name along and it will be looked at — if the check logic is at fault, it gets fixed.
