Each morning they want to know which sites were down overnight and which TLS certificates are close to expiring, before a client calls about it. Monitoring services do this for a monthly fee per site. The agency already has a Linux server, a text file of domains and a shell script that checks one site, and would rather not add anything bigger than that.</p>
