-A Health Check is a service that runs on Cloudflare's edge network to monitor whether an origin server is online. This allows you to view the health of your origin servers even if there is only one origin or you do not yet need to balance traffic across your infrastructure.
+A health check is a service that runs on Cloudflare's edge network to monitor whether an origin server is online. This allows you to view the health of your origin servers even if there is only one origin or you do not yet need to balance traffic across your infrastructure.
 
 Health Checks support various configurations to hone in on what you can check, including response codes, protocol types, and intervals. You can specify a particular path if an origin server serves multiple applications or check a larger subset of response codes for your staging environment. All of these options allow you to properly target your Health Check, providing a precise picture of what is wrong with an origin server.
