Cold starts: why the first visit takes 10 to 30 seconds
An app on the App plan scales to zero when nobody visits it. The first visit after a quiet period then starts the container, which takes 10 to 30 seconds (measured: about 22 seconds for a fresh Next app). After that, requests are answered in a fraction of a second until the app goes quiet again.
This is not an outage and the monitoring treats it that way. It is the trade-off that keeps the App plan at € 15: you only use compute while someone is there.
Do not want to wait? Switch on the add-on "Always on" under your site's settings in the portal: € 9 a month, and the container keeps running. On the Platform plan you get the same by giving a container a minimum of one instance, at the rate on /rates. More in Why is my app slow after being idle?
