I’ve been using this for several servers for about 18 months now. Very reliable. They recently launched a nice redesign. Love that it’s mobile only (except the helpful weekly summary report emails).
Just wanted to introduce myself, I am one of the founders of Vigil. Vigil is an easy to use but very powerful app for monitoring the health of your website. Vigil will send you push and email notifications as well as detailed info about our response time and which part may be slowing you down. The Vigil team is dedicated to making sure that you are the first to know about your site being down. Any questions or feedback are greatly appreciated. Stay Vigilant!
