This afternoon between 1:15 and 4:45, our servers were targeted with DoS attacks that forced our hosting provider, Linode, to null route some of our public IPs.
We now have much better shielding outside of the data center that hosts our site, and we're more aggressively filtering bots. With this in mind, please verify that your API requests aren't getting blocked. If they are, follow the "Contact support" link on our
support site and include the IP addresses you would like to have whitelisted.
Sorry for the outage,
