Allow our checks through your firewall

If your site blocks unknown visitors, allow our checks so they are not mistaken for an attack. There are two ways to recognise them.

By address

Each location that has fixed addresses is listed on the locations and addresses page, always up to date. Allow the addresses of the locations your monitors use. Locations without fixed addresses cannot be allow-listed, so choose a fixed location for monitors behind a strict firewall.

The same list is available for scripts and firewall tools as one address per line, and from inside the app under Monitors, ... , Addresses to allow.

By User-Agent

Our checks identify themselves as:

UptimeWave/1.0 (website availability check)

We announce a change of addresses ahead of time.
