The Quantopian website is back up and fully functional. We'll continue to monitor the site for any further complications resulting from the widespread DDOS attack on our DNS provider. We will update this incident when we feel confident that the site is stable or if there are further issues.

Due to the DDOS attack against our upstream DNS provider, we are unable to guarantee the viability and consistency of our live trading infrastructure. Additionally, users are unable to reliably access their Live Algorithms dashboard on the site. Therefore, we've decided to stop all currently running live trading servers. We will be in contact with our directly affected users shortly.

Our DNS provider is undergoing a denial of service attack. Functionality of the Quantopian website is degraded while they work to mitigate the attack.

Live trading servers are functional but some algos were affected by this outage. The affected algos will have a late start today. Please visit your dashboard at "My code" > "Algorithms" > "Live Trading" if you want to check the status or if you need to stop your algorithm.
