  1. investigating Oct 20, 2025, 02:26 PM UTC

    Some Hightouch services are showing higher error rates and latency due to an upstream AWS outage in the us-east-1 region. Syncs from Databricks, Redshift and Snowflake instances in the us-east-1 region are more significantly impacted.

  2. investigating Oct 20, 2025, 02:26 PM UTC

    We are continuing to investigate this issue.

  3. monitoring Oct 20, 2025, 04:48 PM UTC

    As we continue to monitor, we can provide additional clarity on impact: - Hightouch Events: Reduced availability; events from SDKs may not be captured in us-east-1 - Functions: Experiencing disruptions in us-east-1 - Sources + Destinations: Warehouse and destinations are affected, with potential duplicate event delivery to some streaming destinations. We are actively working to restore full service and will continue to provide updates as the situation evolves.

  4. monitoring Oct 20, 2025, 09:59 PM UTC

    Some Hightouch customers may be continuing to experience slow syncs or syncs that do not start on time. This is due to an upstream outage in the AWS us-east-1 region that is impacting Hightouch as well as some of our integration partners. Please do not attempt to cancel and restart syncs as this will disrupt your position in the queue. We will continue to update you as the situation progresses.

  5. monitoring Oct 20, 2025, 11:35 PM UTC

    AWS has recently completed remediating the underlying outage. Hightouch and our integration partners are working to ensure a return to normal operations as quickly as possible. Please do not attempt to cancel or restart syncs at this time. We will update you again within two hours.
