How this log is built: our monitors probe slack.com around the clock; an outage opens after two consecutive failed checks and resolves after two consecutive successes, so blips don't inflate the record. Only resolved outages appear here — this page is generated from our measured probe data, not user reports, and covers the period since we began monitoring this service.
