Every day for the last couple weeks has been a record traffic day for us at Quizlet. It’s awesome to see so many people using Quizlet — we now have over 500,000 registered users and 3,000+ new ones per day. Quizlet users have uploaded more than 33,000,000 flashcards. Our traffic has grown 80% just over last week. Nice work, guys!

Some of you may have noticed some spotty service on Quizlet in the last few days. We’ve simply become overloaded with our popularity. Unfortunately for us, that means we have to bring the site down briefly to add more server capacity. We’re going to do this sooner rather than later — i.e. TODAY!

We’re expecting to go down around 5pm EST for as many as 5 hours (if all goes well, it’ll be less). We’ll be keeping everyone updated on our quizlet twitter feed. We know it’s short notice and extremely inconvenient, so thank you very much for your patience.
