Datto Networking - DSE Subscribers Throttled Prematurely Despite Available Pooled Data – 2026-09-17 

Summary: Between 2026-09-17 02:00 PM UTC and 2026-09-17 05:00 PM UTC, Datto Secure Edge users experienced throttling despite the network's pooled data cap remaining below the configured threshold. 

Root Cause:  

A subset of users experienced service disruptions during transaction processing, resulting in intermittent access failures and degraded performance. The issue was caused by a temporary misalignment in service controls during a platform transition, which led to unexpected capacity constraints affecting a portion of subscribers. The condition was fully resolved following the deployment of the updated service architecture, which aligned resource management and eliminated the identified risk exposure. 

Incident Timeline:  

• Identified: 2026-09-17 02:00 PM UTC  

• Public Notification: 2026-09-17 04:05 PM UTC  

• Resolved: 2026-09-17 05:00 PM UTC  

Preventative Measures: To reduce the likelihood and impact of similar incidents in the future, we are taking the following steps.   

• Integrate deployment sequencing and migration risk reviews into release planning for changes involving data transitions or dependent services to reduce implementation risk and service impact. 

• Implement post-deployment validation and monitoring to identify unexpected service restrictions and ensure resources are allocated appropriately to eligible users.
