Quizlet will be temporarily unavailable for about five hours starting around 12 noon PT this Saturday, August 1.
We're making some changes behind the scenes that will improve stability as Quizlet continues to grow. Your account data and study content will remain safe and secure, and you'll see the same Quizlet you know and love when things are back up and running.
It will still be possible to create and study sets in offline mode on our iOS and Android apps as long as you've installed and logged in before maintenance begins at 12 noon PT, at which point our full website and online mobile features (including search and feedback) will be down.
We don't expect maintenance to take more than five hours or so (of course, we can't make any promises), and we'll provide more information on Twitter if we anticipate longer downtime.
UPDATE: Maintenance is over and everything's back to normal. Thanks again for your patience and understanding, and have a great weekend!
