How these numbers are made
Each listing is called on a schedule without paying. Listings with usage or a verified owner are checked about every 30 minutes, others about every 6 hours. Uptime is the share of passing checks over 30 days, averaged across this provider's listings. Trust scores follow the published method. The figures on this page can be a few minutes behind the latest checks, and listings hidden after review aren't counted.
