Visits from WWW-Check-Bot in your logs come from this service.
The bot requests a URL that the owner of a website has added for monitoring, at regular intervals of every 1 to 60 minutes. It makes ordinary GET or HEAD requests, follows at most five redirects and reads at most 2 MB of the response when looking for a keyword. It doesn't fill in forms, sign in or follow links.
During outages, and on a schedule chosen by the owner, the bot also takes a snapshot of the page using a regular headless Chrome browser. The snapshot is stored for the owner of the monitor.
WWW-Check-Bot/1.0 (+https://wwwcheck.se/bot)Monitors are only added by the person responsible for a site. If you still get traffic you don't want, you can block the bot by its User-Agent, or contact us and we'll turn the monitor off.
