The scan process works as follows:
During this time, the certificates discovered during customer A’s scan will be available to both customer A and customer B since they are both within the 8-hour results period.
Customer C will only be able to see the rescan of Customer B’s certificate since the 8-hour period has elapsed.
Rescans triggered by customers are only initiated every 8 hours and the same site or domains are not scanned if this was done within the 8 hours of the scan.
The Customer will only get the cached scanned results during this period.
