Monitoring

Real-time segmentation was fully restored today as planned and all systems are currently operating without delays. Outstanding delays in recipients entering event-triggered flows were resolved by 9:30PM EST on 11/26. We are running a complete update of all segments now to guarantee accuracy. We continue to monitor all systems.

Update

Manually created and updated segments are processing as expected. Segments for scheduled campaigns are accurate and updating ahead of campaigns as expected. Event-triggered flow delays are improving and we will be sending as expected within the next few hours. We will restore real-time segmentation on the morning of Tuesday, November 27th. We'll provide an update when everything is fully caught up.

Update

Manually created or updated segments are inconsistently delayed and are almost processing as expected. Event-triggered flows and real-time segments continue to be delayed. We will provide periodic updates here.

Update

We are now processing manually created and updated segments. Event-triggered flows and real-time segments continue to be delayed. We're actively working on this and will provide another update here soon.
Posted Nov 26, 2018 - 13:53 EST

Update

Due to high volume, event-triggered flows are delayed by 1-2 hours. All new segment creation and existing segment updates are currently paused. We're actively working on this issue and will provide another update here soon.
Posted Nov 26, 2018 - 13:03 EST

Update

Due to high volume, reprocessing segments for scheduled campaigns is currently 1 hour behind. Analytics processing is approximately 30 minutes delayed, which will cause new segments to be slightly out of date. We're closely monitoring the situation and will provide another update here shortly.

Update

Due to increased activity around Cyber Monday, real-time segments will only update a few times a day. For any campaign set to update recipients at send time that is sending to one or more segments, we will automatically reprocess those segments in the hour leading up to the send time to ensure accuracy. Any new segments you create will be immediately correct. We expect real-time segmentation to be restored on Tuesday, November 27th.

Update

Real time segmentation continues to be delayed so existing segments will be refreshed periodically throughout the day. Any new segments you create will be immediately correct. We'll continue to provide updates here.
Posted Nov 25, 2018 - 09:31 EST

Update

All flows are sending without delay. While real-time segmentation is still experiencing delays, we are actively refreshing all segments and expect that by later tonight all segments will have completed. We will continue periodic reprocessing of all segments and will provide updates here.

Update

Flows and new segments continue to process accurately, and live flows are sending without delay. There are intermittent delays in manual flow scheduling, and real-time segmentation continues to be delayed. As a result, segment-triggered flows may not schedule the correct recipients if the segment is out of date. We are continuing to work on this issue and will provide updates here.

Update

Flows are processing accurately and are facing intermittent delays. Real-time segmentation continues to be delayed. We are continuing to work on this issue and will provide updates here over the course of the weekend.
Posted Nov 24, 2018 - 08:29 EST

Update

We are actively monitoring all systems and expect that flow triggering and real-time segmentation will fully catch up to real-time overnight. We will provide an update in the morning.

Update

We are continuing to work on a fix for this issue.
Posted Nov 23, 2018 - 19:19 EST

Update

Due to sustained high volumes of incoming integration and email events, real-time segmentation and flow triggering remains delayed by several hours. We continue to actively work on this issue to help our systems catch up and will provide updates here.
Posted Nov 23, 2018 - 18:53 EST

Update

We continue to experience delays in integration and email event processing. As a result, real-time segment updates may be delayed by a few hours. Additionally, users may see some inconsistencies in flow filtering or segment membership. We are actively working on this issue.
Posted Nov 23, 2018 - 16:00 EST

Update

We continue to see roughly 1 hour delays in real time segmentation and event-driven flow triggering. We will provide another update shortly.

Identified

We are currently seeing delays between 1-2 hours for real-time segmentation processing & flow triggering based on incoming events such as opens, clicks, and purchases. We have identified an optimization to improve event processing performance and will provide another update within the next hour.

Investigating

We are currently investigating delays in real-time segmentation processing & flow triggering based on incoming events such as opens, clicks, and purchases. We will provide an update within the next hour.
