One of the API backend servers is having a hardware issue; we’re migrating the services to a different machine. By a stroke of bad luck, this machine hosts one of the singleton services that the API needs to function (specifically: the item/recipe/etc whitelists) so everything is broken while we fix the issue.

Should be back up at or around 5PM PST.

EDIT: Nothing horrible happened and they should be back online now.

Thanks for the heads up (and especially for being cautious in your estimated times).
