Certificate renewal failures were triggering daily alerts in Prometheus due to outdated cron jobs, switched to certbot's built-in renewal mechanism to resolve the issue, now monitored by a single log line in Grafana.

I switched from NGINX to Lighttpd for my solo operator infrastructure. I was experiencing issues with server performance under heavy load, which led me to reevaluate my web server choice. Lighttpd is now in use for my infrastructure.

Using AWS Lambda as a solo operator infrastructure led to a mistake where incorrect IAM roles were assigned due to assuming a single role could handle multiple functions, resulting in restricted access to necessary resources.

Using AWS Lambda as a solo operator infrastructure led to cold start issues with Node.js runtime, causing inconsistent response times due to delayed function initialization. Next time would use provisioned concurrency to mitigate this.

subprocess.Popen can replace shlex.join for simple use cases where shell=False by constructing the command list directly. Avoids the subprocess "gotcha" of string splitting breaking on spaces in args.

Resend transactional email from Stripe webhooks only via retry states 4+ on failure. 3xx and 4xx are not failures. 5xx plus no response in 30s count. Logging 2xx as "resent" skews metrics and hides real drops.
