What is updown?

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

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 and they must be whitelisted. You can also get the list of nodes or IPs from the API to automate this part, check out the /nodes endpoints. Also don't forget to enable the "IP whitelisting" option in your setting if you want, in order to be notified of IP changes and be excluded from new locations by default.
