Beginning at 1:45 PM US Eastern, we began observing degraded functionality which led to the following issues:
Delay in Processing Subscription Events Delay in Schedule Forms being published Delays in Email and SMS message sending, including double opt-in messages Delays in event processing and associated Flow message sending Delays in lists and segments loading, as well as list imports Delays in outbound events to integrations Degraded ability to schedule campaigns
Our engineering team is actively working to mitigate the issue. We will provide more updates as we have them.
