Amplitude Outage

At 4:49pm PDT on April 2 2024, Amplitude’s US data center experienced a service interruption after a series of metadata tables were accidentally deleted. Customers on the US data center were unable to access the Amplitude platform—including Analytics, CDP, Experiment, and Session Replay. Our EMEA data center was not impacted.
The service came back online at ~11.30pm PDT the same day, and we began processing the data received—but not ingested—during the outage. As a result, there was a lag in performance and/or limited availability of a small amount of metadata for some users as we worked to fully restore the service.
As of 12:15am PDT on April 4 2024, Amplitude is running at full capacity and we are conducting a full root cause analysis to ensure this doesn’t happen again.

A small percentage of the metadata, including event types or property names introduced between 12:30pm and 5:00pm PDT on April 2, may still be temporarily absent from charts and dashboards. We expect this issue to be resolved by Thursday, 4/4. We will provide another update by 9am PT.

A small percentage of the metadata, including event types or property names, introduced between 7:10am and 5:00pm PDT on April 2 may still be temporarily absent from charts and dashboards. We are continuing to work on this issue and will provide another update at 6:00pm PDT.
