About

What is updown?

updown is an online service that checks your website's status by periodically sending an HTTP request to the URL of your choice. It then notifies you by email or sms when your website is not responding correctly.

Another monitoring website?

Yes, there are a few existing alternatives but I was looking for a service really simple, cheap and nice looking. I couldn't find any, that's why I decided to build one the way I want. If you think something's missing, don't hesitate to leave your idea with the "feedback" button at the bottom.

Where are updown servers?

There are currently 8 monitoring nodes, requests to your servers will come from these IPs. You can also get the list of nodes or IPs from the API to automate this part, check out the /nodes endpoints.

If you whitelist these IPs, don't forget to enable the "IP whitelisting" option in your settings in order to be notified of IP changes and excluded from new locations by default. Otherwise you may get false positive results.
