Uptimia Web Health Index
The Uptimia Web Health Index scanner
It checks whether public websites are online and set up correctly, for the Uptimia Web Health Index. If it visited your site, here is what it requested and how to stop it.

The short version
What a site owner or a firewall admin needs to know.
What it requests
The scanner checks the address of your home page. It does not crawl your site.
One GET request to your home page from one of our monitoring locations. It follows at most 5 redirects, reads the response headers and at most 16 KB of the page, then closes the connection.
Other locations run up to 2 more checks within 3 minutes to confirm the failure. They can start right after the failed check.
Your robots.txt, your DNS records (NS, MX, SPF, DMARC and CAA), your TLS certificate (up to 2 TLS handshakes), and the redirects from http to https and between www and the bare domain (4 GET requests, redirects not followed).
Checks on your site start at least 60 seconds apart, except the confirmation checks after a failed check.
- Fills in forms or logs in
- Runs JavaScript
- Crawls pages or follows links
- Sends any method other than GET
It does follow redirects from your home page, up to 5.
Read from the public RDAP registry service at the start and at the end of a measurement period. This sends no request to your server.
IP addresses
The scanner sends requests over IPv4 only, from the addresses below. The list is built from the monitoring locations that run the scanner right now.

The scanner runs on some of the same locations as Uptimia's monitoring bots, so a monitoring allowlist also lets it through.
How to opt out
Use either method. Both take effect within 24 hours.
Add these two lines to your robots.txt. If the file disallows UptimiaHealthIndex for your home page or the page it redirects to, we remove your site from the scan. Without a UptimiaHealthIndex group, the rules for User-agent * apply. The scanner reads robots.txt before its first check and once a day after that. A missing robots.txt (404) means no rules. If the file cannot be read (429, a 5xx error, a timeout or a file over 512 KB), the scanner tries again an hour later and does not start checking your site until it has read the file. If 48 hours pass without a successful read, the scanner pauses its checks of your site until it can read the file again.
