website down alerts
Website down alerts with downtime notifications by SMS, email and Slack the second your site fails
The point of a down alert is simple: know your site is down before your customers tell you. AlertPing checks your site from two regions, confirms the outage is real, and sends a website down alert by SMS, email, Slack or webhook within seconds. No more finding out from an angry email or a drop in orders. Flat from $49 a month, with 30-second checks from $59.

the reason
The first person to know should be you, not a customer
Most teams learn their site is down the worst way: a customer emails, sales pings you, or orders quietly stop. By then the outage has been running for an hour and the damage is done. A down alert closes that gap. The moment your site stops responding, the alert reaches your phone, so recovery starts in minutes instead of after the first complaint.
That only works if the alert is fast and trustworthy. An alert that takes five minutes to fire, or that cries wolf every time one region has a hiccup, trains you to ignore it. AlertPing checks every 30 seconds on Team and up (60 seconds on Starter) and confirms an outage from a second region before it pages you, so the alerts you get are worth acting on.
how you get told
Get the alert where you will actually see it
Different outages need different channels. A 3am database failure needs an SMS that wakes someone; a daytime blip is fine in Slack. Every channel below is included on every plan, with no separate credit balance to top up.
SMS
A text to your phone the second an outage is confirmed. The channel people actually notice out of hours, included on every plan.
A clear down alert with the failing check, the error and the time, so the responder has context before they open a laptop.
Slack
Alerts posted straight into the channel your team already watches, so the whole team sees the outage and the recovery together.
Webhook
A JSON payload to your own endpoint to trigger PagerDuty, a runbook, an auto-restart or anything else you have wired up.
how it works
From failure to alert in under a minute
-
Step 1
Add your URL
Paste your website address and choose who gets alerted. Setup takes under a minute, no agent to install.
-
Step 2
We check every 30 to 60s
AlertPing requests your site around the clock and watches for errors, timeouts and wrong responses, not just a dead connection.
-
Step 3
Two regions confirm
Before paging you, a check from a second region confirms the site is really down, not just unreachable from one place.
-
Step 4
You get the alert
SMS, email, Slack or webhook fires within seconds, with the details you need to start fixing it right away.

what triggers an alert
More than just a site that will not load
A site can be broken while still technically responding. AlertPing alerts on the failures that matter, not just a dead connection.
| Failure | What the visitor sees | The alert you get |
|---|---|---|
| Server down or timing out | Spinning page, then an error | Down alert within 30 to 60 seconds |
| 500 or 503 error | An error page instead of the site | Alert on the wrong status code |
| Blank or broken page | A page that loads but is empty | Alert when an expected word is missing |
| Expired SSL certificate | A browser security warning | Advance warning before it expires |
| Slow response | A page that crawls | Alert when response time crosses your limit |

what a down alert costs
What downtime alerts and notifications you get on each plan
Most services that notify you when a website is down meter the part you need most. SMS comes out of a credit pack, fast intervals sit on the top tier, and phone calls are an add-on. On AlertPing every downtime notification channel below is part of the plan price, and the only things that change as you move up are how many monitors you run, how often they check and who gets paged.
| Downtime alert feature | Starter, $49 | Team, $59 | Business, $189 | Enterprise, $378 |
|---|---|---|---|---|
| Monitors | 20 | 100 | 500 | 1,500 |
| Check interval | 60 seconds | 30 seconds | 30 seconds | 15 seconds |
| Downtime alert email | Included | Included | Included | Included |
| SMS down alert | Included | Included | Included | Included |

How do I get notified when my website is down?
Add the URL to an uptime monitor and choose where the notification goes. AlertPing requests the page from US East and EU Central, and when both see a failure it sends the down alert by SMS, email, Slack or webhook within seconds.
Can I get a downtime alert by email?
Yes. Every plan sends a downtime alert email that names the monitor, what failed and when the outage started. Most teams pair email with SMS so an outage at 3 a.m. reaches a phone and the email becomes the written record.
Why do downtime notifications sometimes arrive when the site is fine?
Usually because one checking location had a network blip and the monitor alerted on a single failed request. AlertPing only notifies when a second region confirms the failure, which removes most of those false alarms without slowing the real ones down.
How much does a website down alert service cost?
Paid services run from about $10 to over $100 a month depending on monitors, interval and whether SMS is metered. AlertPing is $49 a month for 20 monitors with SMS included, and $59 for 100 monitors at 30 seconds. Our uptime monitoring pricing comparison lines up fifteen vendors.
questions
Website down alert questions, answered
How do I get an alert when my website goes down?
Use an uptime monitor that checks your site on a schedule and notifies you when a check fails. With AlertPing you add your URL, pick a channel like SMS, email or Slack, and the service checks the site every 60 seconds on Starter or every 30 seconds from Team, from two regions (US East and EU Central). When an outage is confirmed, the alert fires within seconds, so you hear about it before your customers do. The full setup, channel by channel, is in how to get alerts when your website goes down.
Can I get an SMS when my website goes down?
Yes. AlertPing sends a text message the moment an outage is confirmed, and SMS is included on every plan with no separate credit pack to buy. SMS is the channel most teams rely on out of hours, because it reaches a phone even when nobody is watching a dashboard or a Slack channel.
What is the best website down alert service?
The best service for you is the one that alerts fast, does not cry wolf, and reaches you on a channel you watch. Look for short check intervals, multi-region confirmation to cut false alarms, and SMS included rather than metered. AlertPing does all three at a flat price; compare the field on our best uptime monitoring tools roundup.
How fast will I be alerted?
AlertPing checks every 30 seconds on the Team plan and up, and 60 seconds on Starter, then confirms the outage from a second region before paging. In practice that means a down alert reaches you within roughly 30 to 90 seconds of your site failing, fast enough to start recovery before most visitors even notice. Picking the right interval for your own uptime target is covered in how often you should check uptime.
