In OpenStack deployments using Neutron with the OVN ML2 driver, ports could be bound to agents that were not alive. This behavior led to virtual machines experiencing network interface plug timeouts during provisioning, as the port binding would not complete successfully.
The OpenTelemetry Collector may intermittently fail to export telemetry data when the backend API is unavailable or overloaded. These failures manifest as timeouts (`context deadline exceeded`) or transient HTTP 502 responses. While retry logic is typically enabled, repeated failures can introduce delay or backpressure.
NGINX reports an upstream timeout error when it cannot establish or maintain a connection to backend services within the configured timeout threshold.
