We use an uptime monitor. Who offers an SMS alert integration for downtime?

If you mean uptime-monitoring services that can send downtime alerts by SMS, several do:

• Twilio — commonly used as the SMS delivery layer if your monitor supports webhooks; UptimeRobot, for example, supports webhooks on Team/Scale plans.UptimeRobot Help Center

If you tell me which uptime monitor you currently use, I can identify the simplest SMS option for it.
