US datacenter: endpoint sensors unable to connect (2026-09-19)

This incident is being reported retroactively.

Starting at approximately 21:50 UTC on 2026-09-19, endpoint sensors connecting to our US datacenter progressively lost their connection to the LimaCharlie cloud. By 22:08 UTC nearly all sensor traffic to the US datacenter was affected. Other datacenters (Canada, Europe, UK, India, Australia) were not impacted.

Our connectivity alerting paged the on-call team at 22:17 UTC and engineers began investigating.
