In an effort to continually improve our service, we will be performing scheduled maintenance on a small portion of the API today from 2pm EST and lasting around 15 minutes. During this time, integrations or clients of the Public API requesting a sorted list of subscribers for a list will experience a service interruption. Specifically, the HTTP GET requests for the Subscriber Collection will be unavailable. We are making modifications to improve the way in which the subscribers are sorted in order to make this more consistent and useful to our users. Thank you for your patience and understanding.
