Outage prompted team to instrument API gateways and background workers with OpenTelemetry — Dave Augustus

- Dave Augustus said his team added OpenTelemetry traces to API gateways and background workers after a Twilio/WhatsApp debugging incident exposed hidden failures. (x.com) - They instrumented request IDs across queues and workers so errors could be traced end-to-end instead of only as isolated logs. (x.com) - New cloud engineers should learn OpenTelemetry primitives to tie logs, metrics, and traces together for faster incident resolution. (x.com)
