As someone that has hosted with WP Engine since early 2012 I'm still coming out ahead. The day our agency moved all sites there was the day we stopped dealing with hacks and security issues. We used to spend a chunk of every month cleaning up one site or another. It was awful.

I see resetting a bunch of passwords as no problem at all when compared to the work they have saved us over the years.

Keep up the good work WPE. Sorry you're going to have a crappy couple of days. You'll be that much stronger on the other side.
