It looks like Wikidot.com was not the only one affected: several popular services that depend on AWS were taken down, including Reddit, Coursera, Flipboard, FastCompany, Heroku, Airbnb, Github, VYou, Foursquare, Pinterest and many more.
Shame this happened, but we learned how to manage such critical situations at Amazon Web Services. We will try to automate as much of failover procedures as possible to prevent such situations.
It is also important to note that despite the outage there was not even a slightest risk of losing any data. And by looking at duration of outages of other services, we did pretty well.
