Recently I saw a message on an Ontraport FB group that mentioned how downtown was killing the confidence of the person posting. While this hasn't been much of an issue for my clients, I still think monitoring is a going to be a great tool. If for some reason a sequence doesn't fire off, you'll know why! ( Unless it was human error of course ) It's now a few days later and it looks like Ontraport has partnered with pingdom to provide a client notification system. If you use Ontraport go here and enter your cell phone so you can be informed of outages.
I can't rave enough about how much I trust Ontraport and their customer service is amazing.
I know they are in the process of upgrading their servers and working through some rather large growth spurts so it's good to see them tackling this on both ends.
