AHJ Radar · Mason Mathews Facility Assurance, LLC

Our source monitor

AHJ Radar helps building owners and managers keep up with fire, building, elevator, boiler, pool, lodging, workplace and environmental rules. To tell them when an official rule page changes, a small program reads those public government pages and notes when their text changes.

How it identifies itself

Every request carries the user agent AHJRadarSourceMonitor/1.0 (+https://ahjradar.com/monitoring/; radar@ahjradar.com). It does not pretend to be a browser or a person.

What it reads, and how often

• Only public pages, the ones listed as official sources in our state records: code-adoption pages, rule pages, statutes and program pages.
• Each page about once every nine hours. It reads a page once, and once more after a pause only if the first try timed out or the server said it was busy.
• It never signs in, submits a form, solves a challenge or follows links beyond the listed page.

It follows your robots.txt

Before reading a page the monitor reads the site's robots.txt (once a day) and skips any page it disallows, for our name (AHJRadarSourceMonitor) or for every robot. When a site refuses automated reading, we do not try to get around it: we look for an official copy published elsewhere, and our pages tell readers to confirm on the agency's own page.

For agencies and site owners

If you would like us to read less often, to read a feed or an email bulletin instead, or to stop altogether, write to radar@ahjradar.com and we will change it. If your site blocks automated readers and you are willing to allow ours, the user agent above is the one to allow.
