Notifications when the website is broken

Hi all!

I have a NextJS app on Netlify. Yesterday there was an issue with loading pages. The browser was trying to load a page for some time then shows the message “Inactivity timeout. Description: Too much time has passed without sending any data for document”. Different users experienced problems for one hour then everything became fine. I know, there are function logs and Edge Handler logs but they are available only in one hour.

Is there a way to research this incident somehow?
For future. Is there a way to notify developers when the site at the moment does not work properly and the users can’t see the pages?

You might want to check out the many third-party website monitoring services to see if any of them meet your needs.

Here’s just one of them:

Hey there @geolocker78 ,

Welcome to the Netlify Forums :netliconfetti:

“Inactivity timeout. Description: too much time has passed without sending any data for document” is not a message our platform sends. Are you able to find the source of it in your source code?

If you are seeing issues on your end, it would be useful if you could gather a HAR file. This will let us see what you are seeing, after the fact, and includes details we would need to see what our service was doing when you received this error.

Let me know if this is helpful!
