This incident has been resolved. All systems are operational.

The issue has been identified and resolved. Event processing and associated Flow message sending as well as outbound events to integrations are back to real-time.

Engineering will continue to monitor the results.

We are continuing to investigate this root cause of the issue. Around 9:05 AM US Eastern, we fixed a few delays in our systems.

Email and SMS message sending, including double opt-in messages is real-time
Profiles being added to lists and segments loading is real-time
Unique coupon codes in forms is functional

The following are still impacted:
Delays in event processing and associated Flow message sending still happening

Our team is looking into the issue further and will continue to provide updates.
