How to Get Alerted When a Server Goes Down (Email, SMS, Call)
Summarize with ChatGPT Claude To get alerted when a server goes down, run a check from outside the server and send its result to a channel that reaches a human. That check can be a cron script on a second machine that pings the host and tests a port, an external ping or TCP port monitor, or an agent on the server whose silence opens an incident. Email and Slack are fine for the record. For a server that matters at 3am, the alert has to escalate to SMS and then a phone call when nobody acknowledges it.
