I was working on a client's project, and we finally got their website live. Fast forward a year, and I completely spaced on renewing the domain, so the site just disappeared, and I didn't even notice. Thank goodness, Notify Me caught the outage and pinged me with an email, so I was able to jump on it and get everything sorted out quick. Seriously, what a game-changer! It's saved my skin more than once.
