What should a small team do when the alerting channel itself goes down during an outage?

One Channel Means One Point of Failure

Draw the path an alert takes in your team and it is usually short: the monitor fires, it posts to a chat workspace or hands the alert to a notification service, that service sends a push notification, and a phone on a nightstand buzzes. Four hops, and most teams have exactly one instance of each. Worse, those hops share dependencies you did not choose. The push notification rides the same mobile platform infrastructure for everyone on the team. Two of your three engineers may be on the same carrier. Your monitor and your chat vendor might sit in the same cloud region, which means a regional event can take out the thing being watched and the thing doing the watching at the same moment.

The self-inflicted versions are just as common and much quieter. A webhook URL expires after someone rotates an integration. SMS credits run out because the card on file was replaced. An alert channel gets muted at night by a well meaning person during a noisy week and never unmuted. The one phone number in the escalation policy belongs to an engineer who left in March. None of these announce themselves. The dashboard looks fine, the monitor believes it delivered, and the first person to learn about the outage is a customer. That asymmetry is the whole problem: a broken service screams, a broken alert path is silent.

Build a Second Route That Shares Nothing With the First

A backup channel only helps if it is independent in the ways that matter. Aim for a different vendor, a different transport, a different network, and a different device. If the primary is a push notification from a chat app over wifi, a good secondary is an automated voice call or an SMS from a separate provider over the cell network. A voice call is a strong last resort because on most phones a repeated call from a contact marked as a favorite or emergency will break through do-not-disturb, which is exactly the condition under which alerts go missing. Running the secondary from a different cloud region than the primary is worth the small extra effort too. Related: How to Set Up Alerting That Avoids False Alarms

Keep the second route deliberately boring. It should carry only alerts that genuinely justify waking a person, with the shortest possible message: what is down, since when, and a link. If you let routine noise onto the backup channel, people will silence it within a month and you are back to one path. Document who the route reaches and keep that contact list somewhere reachable when your tools are not, such as a printed card in a drawer and a shared note in everyone's phone contacts. One rule matters above all the rest: do not chain the backup through the primary vendor's webhook, or you have built a second front door with the same lock.

Make Silence Itself an Alarm

The strongest protection against a dead alert path is a heartbeat, sometimes called a dead man's switch. Your monitoring system, or a job running next to it, pings an independent service on a fixed schedule. If that ping stops arriving within the expected window, the independent service raises an alarm through your secondary channel. It is a small piece of plumbing that inverts the logic of everything else you monitor: instead of waiting for bad news, you treat the absence of good news as the signal. That single check catches the failures nothing else catches, including the monitor crashing, the alert queue backing up, and the account being suspended.

Then prove the whole thing works on a schedule, because an untested backup is a guess. Once a month, send a real test alert down every route and confirm that each person actually received it on the device they expect to be woken on, then write down how long it took. Once a quarter, run it at an inconvenient hour, since the middle of the afternoon proves very little about the middle of the night. Re-test after every phone upgrade, number change, vendor migration, and new hire, and add the test to your onboarding checklist so a new engineer's first week includes being paged once on purpose.

What to Do When the Alerts Go Quiet

In the moment, assume the worst and verify independently. Load your own product from a phone on cellular data rather than from the office network, check whatever external view you have of your service, and if you host a status page on separate infrastructure, confirm you can still publish to it. Manually run the handful of checks that matter most: the login flow, the main API endpoint, the payment webhook, the nightly job. Give one person the job of talking to customers while the other one digs, even if your whole team is two people, because the alternative is two engineers debugging in silence while the inbox fills up.

Afterwards, treat the delivery failure as an incident in its own right, separate from whatever was actually broken. The most useful number to record is detection latency, meaning the gap between the first failed request and the first human who knew, because that gap is what your backup routing is supposed to shrink. Write the short postmortem, add the route that was missing, and take the opportunity to delete the low value alerts that trained everyone to ignore the channel in the first place. Alert paths decay quietly, so the habit of checking them is more valuable than any particular tool you pick. Related: How to Write a Clear Incident Update Your Customers Trust
