It’s disconcerting when a large provider is brought down. We experienced the issue firsthand when our website and a couple of client sites were affected. In addition our DNS is hosted at Godaddy so, even though our email is in the Office 365 Cloud at Microsoft, some messages bounced back because the mail server address could not be found.

Godaddy is a huge provider of a variety of internet services and their performance and support have been exemplary. They responded quickly and tirelessly until the situation was resolved and you can bet that this particular scenario will not happen again.
The bottom line is this: Things happen, do everything in your power to prevent them from happening but be ready when they do…
