Our uptime checks run every minute from a location of your choice. Once we have confirmation that your site is down, we'll notify you instantly.
We'll alert you if your site goes down
There are many reasons a site can go down.
- Human error
- A faulty deploy
- Lack of network connectivity
- High load on the server
- Domain name offline
- DNS resolving issue
HTTP/1.1 500 Internal Server Error Server: nginx Date: Tue, 21 Sep 2021 07:35:35 GMT Content-Type: text/html Content-Length: 531 Connection: keep-alive
Whatever the cause may be, we alert you instantly. With all the details to help you troubleshoot the problem & fix it.
Via email, SMS, Slack, Discord, ... you name it. We've got plenty of notification options.
Here's how that might look.
The technical explanation of what we monitor
We monitor what truly matters: your application or website.
If we fail to receive an
HTTP/200 response within a reasonable timeframe, we mark your site as
down. When we see website failures for 2 minutes in a row, we send out notifications so you can intervene.
This prevents monitoring flaps and false positives.
You can change the timing threshold in your settings. Prefer to get alerted after 5 minutes instead of 2? Not a problem.
Our downtime reports give you all the details to quickly verify and troubleshoot any alert.
In our report you'll find useful commands to replicate our monitoring, this allows to you see exactly what we see.
Content verification & checkstring monitoring
Is just monitoring a status code not enough? We can verify the existence of a piece of text on the page too
(a so called "checkstring"). If we receive an
HTTP/200, but the checkstring is missing in the source code, we'll mark the site as down.
Monitoring beyond a GET request
By default we monitor using a
GET HTTP call, but you can also change this to
Each method can have its own form payload. This allows you to simulate a form submission and monitor search results, contact forms, API endpoints, ...
You could even perform a website login through a
POST call and verify the account page loads
