Identified - Our internal monitoring systems have alerted us to the fact that some of our customers are experiencing lag in making user profile and event updates. We're aware of the situation and have already taken steps to resolve it. This only impacts one server cluster, which is why only some of our customers are affected. We are expecting that the lag times will decrease over the next couple of hours, and will post back here by 2:30pm Pacific.

Identified - We are currently working on resolving a situation in which the metadata store system is in a degraded state. Specifically, any updates made after approximately 7am Pacific Time this morning will not yet show up. If they were new data, the data will not be available to use, causing outbound messages that are trying to use that data to fail. If they were updates to existing data, the existing data will be used instead.

Campaigns and workflows that do not use the metadata store are unaffected.

Our engineering team has identified that this issue was caused by a storage partition becoming inactive - we're still working on understanding why. The result of this failure was that the metadata store needed to be rebuilt. This process is ongoing, and is expected to take until about 4pm Pacific Time this afternoon. We'll provide an update on this process within the next 90 minutes.

Identified - A subset of customers are experiencing slow processing of events. This can manifest in a number of ways, including slow processing of API calls, workflows processing slowly, delayed emails and analytics lagging behind. Our engineering team has identified the cause, and are working on a resolution. We'll update again by 12:30pm Pacific Time.
