Our engineering team have implemented a fix, which appears to have resolved the cause. There are still delays, but the updates should be back to normal shortly. We'll continue to monitor until the problem is completely resolved.

Subscribers signing up through our HTML subscribe form, subscribe pages or subscribe buttons aren't appearing in subscriber lists as soon as they sign up. Any subscribers unsubscribing from campaigns won't immediately appear as unsubscribed in the respective subscriber lists. These updates are saved and being processed, but this is currently delayed. Our engineering team is working on this now and should have that resolved soon.
