A DNS misconfiguration was identified and up to 50% of all requests were being incorrectly routed and failing as a result. The configuration has been rolled back and the system will resume normal operations as DNS changes propagate through the network.

Everything but API is back up and running at full speed. We expect that to take a few more hours as DNS changes propagate.
