This is a very small feature and wanted to activate it before rolling the bigger update that is being working on.
When a monitor goes “down” first and “up” afterwards, Uptime Robot used to send the info: “The monitor XY (http://www.xy.com/) is back up”.
Right now, it includes the amount of downtime so you won’t have to compare the date-times of the notifications for finding the value. It is now like: “The monitor XY (http://www.xy.com/) is back up (it was down since 1 days, 2 hours, 07 minutes and 57 seconds)“.
Hope you like it : ).
