US - Increased Webhook Latency

Incident Report for Nylas v3

Resolved

Webhook latency in the US environment has returned to normal levels.

We implemented performance optimizations in response to the elevated API traffic identified earlier, and the webhook backlog has fully cleared. Core API performance remained normal throughout the incident.

We will continue to monitor system performance closely to ensure continued stability. Thank you for your patience.

Update

We continue to optimize system performance in response to the increased API traffic identified earlier.

We are seeing a reduction in webhook backlog in the US environment. Sync latency remains elevated while the backlog continues to clear. Core API performance remains normal.

We are closely monitoring progress and implementing additional optimizations to accelerate recovery. Updates will be shared here as they become available.

Identified

We continue to experience increased webhook latency and delays in the US environment affecting a subset of customers.

We have identified a significant increase in API request volume from a small number of integrations, which has resulted in elevated processing latency for Google and Microsoft Graph webhooks. The traffic remains within established rate limits, and core API performance remains normal with no additional request latency.

The impact is limited to delayed notification and webhook processing. We are actively implementing performance optimizations and coordinating with affected integrations to better understand expected usage patterns. Updates will be posted here as they become available.

Investigating

We are currently experiencing increased sync latency in the US environment affecting a subset of customers. This may result in delays of up to approximately one hour for email and calendar updates, primarily for Google and Microsoft accounts. We are actively investigating the root cause and will continue to share updates here.
