When Slack Goes Down: A Survival Guide for Your Team
The team channel goes quiet. Not the normal quiet — the kind of quiet where nobody is posting, reacting, or typing. You type a message and hit send. The spinner appears. And stays. You check your internet. It's fine. You open Slack in the browser. Same spinner. Slack is down — and you have no way to tell anyone.
What Happens on Your Team
The Developer
Notices deployments aren't posting to the #releases channel. Checks the CI pipeline — it completed fine, but the Slack notification webhook is timing out. Tries to message the team about it... on Slack. Realizes the problem.
The real cost: When Slack is down, every bot integration goes silent. CI/CD notifications, monitoring alerts, support ticket notifications — all the automated messages your team relies on stop arriving. If your monitoring sends alerts to Slack, you've lost your alerting during the outage.
What they should have had: A non-Slack alert channel. If your monitoring alerts go to Slack and Slack is down, you don't get alerts. Set up Telegram or webhook alerts as a backup — or primary — channel.
The PM / Team Lead
Sends an email: "Is Slack down for everyone?" Three people reply: "Yes." Two more reply: "I thought it was my internet." The PM switches to a backup — email thread, Google Meet, or a text group — and tries to coordinate.
The real cost: Remote teams lose their primary communication channel. Standups get missed, blockers go unreported, and the team fragments into email threads and side channels. Even a 30-minute Slack outage disrupts a full day's coordination.
What they should have had: A documented backup communication plan. "If Slack is down, check the status page at X, join the backup Google Meet at Y." This turns a 30-minute scramble into a 2-minute switch.
The Remote Team
Half the team doesn't realize Slack is down because they're heads-down coding. They only notice when they try to post a question an hour later. The other half has been in a group text for 45 minutes trying to figure out what to do.
The real cost: Distributed teams rely on Slack as their office. When it goes down, there's no hallway to walk to, no desk to visit. The team splits into whoever happened to be in the same text group and whoever didn't know anything was wrong.
What they should have had: A monitor on slack.com and hooks.slack.com. When Slack goes down, an alert fires to everyone's Telegram — not Slack — with a link to the backup channel.
Why Monitor Slack?
When Slack goes down, team communication stops. Integrations break, bots stop posting, and critical alerts from other tools never arrive. The irony: you can't even tell your team Slack is down... on Slack.

- 1Monitor slack.com and hooks.slack.com — catch both app and integration outages
- 2Never rely on Slack as your only alert channel — if Slack is down and your alerts go to Slack, you get nothing
- 3Set up Telegram as a backup alert channel — it's independent of Slack's infrastructure
- 4Document a backup communication plan — Google Meet link, email list, or phone tree
- 5Bookmark status.slack.com — Slack's official status page
Slack's Official Status Page
Slack publishes real-time status at status.slack.com. Monitoristic doesn't replace this — it complements it. The official page tells you when Slack reports an issue. Your own monitor tells you when your connection is affected, often before the status page updates. You also get push alerts instead of checking a webpage manually.
The Slack outage paradox: the tool you'd use to tell your team about a problem is the problem. Every team that runs on Slack needs a monitoring and alerting system that doesn't depend on Slack. The 30-minute gap between "Slack is down" and "the team knows Slack is down" is entirely preventable with a single alert to a non-Slack channel.
