Our system administrators monitor our servers 24 hours a day, seven days a week. This includes network statistics such as ping, as well many other metrics such as CPU load and memory consumption and will highlight to our team immediately if there are any issues apparent. We do not monitor your website directly, so for this purpose you could use a service like Uptime Robot. This will highlight anything that our server level monitoring might not pick up - such as a plugin issue on your site for example.
