Contact webhook delivery backlog

This incident has been resolved.

The backlog is gone, and all delayed contact webhooks have been delivered. Delivery latency has now recovered. The new infrastructure configurations prevent this same issue from happening again.

We are still noticing increased latency in contact-related webhook deliveries. Events can be delayed by up to 8 hours before being delivered. We have identified the issue and implemented infrastructure changes to process the backlog faster.

We are currently investigating increased latency in contact-related webhook deliveries. At this time, you may experience delays in receiving contact events on your webhook endpoints.
