Slack Downtime Alerts Plus Email, SMS, and Webhook Notifications
An alert only helps if it reaches the right person on the channel they actually watch. Uptimehub sends downtime notifications everywhere your team lives and escalates until someone responds.
Checked from regions with auto-retry. No single-location false alarms.
All systems operational. Steady pulse across every region.
api.example.com returned no response from all 6 regions. Auto-retry confirmed the outage, then we alerted your team.
api.example.com is back up. The incident is logged to your status page history automatically.

In short
Downtime alerts are the notifications Uptimehub sends the moment a confirmed outage is detected, telling you what failed, where, and for how long. You can route alerts to Slack, email, SMS, webhook, Discord, Microsoft Teams, Telegram, and PagerDuty-style on-call, so every team gets notified on the channel they actually watch. Because Uptimehub confirms failures across 6 regions before firing, the alerts you receive reflect real outages rather than transient network noise. Escalation policies let you notify the next person or channel if the first alert goes unacknowledged, so nothing falls through the cracks at 3am. When a service recovers, Uptimehub sends a matching all-clear so you always know the current state.

On-call escalation
If an alert is not acknowledged, Uptimehub escalates to the next person or channel with a PagerDuty-style policy.
Confirmed, not noisy
Cross-region confirmation before alerting means you only get paged for real outages, not one-off blips.
Recovery notifications
A matching all-clear arrives the moment a service comes back, so you always know the current status.

FAQ
Questions buyers ask about Alerts
Connect your Slack workspace, pick the channel that should receive incidents, and assign it to your monitors. When a failure is confirmed across regions, the alert posts with the monitor name, the failing region, the status code or error, and the time it started, followed by a recovery message when the service comes back.
Within seconds of the outage being confirmed. Detection speed is capped by your check interval, so a one minute interval plus cross-region confirmation puts a real alert in front of you inside roughly a minute. Anything slower than five minutes means customers are reliably reporting the outage before your tooling does.
Require confirmation from a second region before alerting, which removes almost all transient network noise. Then check what you are actually asserting: a check that fails on a slow but successful response, or on a redirect you deliberately added, will keep crying wolf. Alert fatigue is a configuration problem far more often than a tooling one.
Yes. SMS is worth reserving for the monitors that genuinely justify waking someone, typically production checkout, login, and your public API. Routing every monitor to SMS is the fastest way to get the whole team to ignore the channel, so pair it with Slack or email for everything below that severity.
A webhook notification posts a JSON payload describing the incident to a URL you control, which lets you route alerts into systems that have no native integration: an on-call rotation, a ticketing system, an internal dashboard, or a script that triggers an automatic failover. It is the escape hatch for any workflow the built-in channels do not cover.
