Set up external uptime monitoring for my app. A hosted service (UptimeRobot, BetterStack, Checkly, Pingdom, or similar) is fine; the goal is that when the site goes down at 3am I hear about it in minutes. Set these up: 1. Monitor more than the homepage. Add checks for the routes that matter: sign-in, dashboard, checkout, the main API endpoint. A homepage that stays green while checkout returns 500s is worse than no monitor at all. 2. For at least the sign-in and checkout paths, use a synthetic transaction check (actually POST a test request, look for a real success response body), not just a ping-for-200. Store the test-account credentials in the monitor's secret store. 3. Set frequency (every one to five minutes for critical paths) and set a location diversity option if the service offers it, so a single-region outage on their side doesn't page me. 4. Configure notifications sensibly: alert only after two consecutive failures to avoid pager fatigue from a single blip. Route notifications to a channel that actually wakes me up (SMS or a real pager, not email). 5. Wire the monitor status into a public or internal status page so I can point users at 'yes, we know' instead of answering ten identical support tickets. Don't monitor every endpoint; pick the five to ten that matter. The deliverable is the monitors configured, alert routing tested by triggering a fake failure, and a link to the status page (public or private).
