Hi all, we have an Umbraco 13 application that is running on an Azure App Service (Linux) instance. Whenever the site restarts, it often takes 5-15 minutes to come back online and occasionally will need to redownload the appsvc/dotnetcore image before the container starts. Any ideas or explanations for this behavior? Thanks! Other relevant info: - Our app is a large multisite, with about 200 sites in the single instance. - We have the Umbraco:Cms:NuCache:UsePagedSqlQuery app setting set to false.

What's the load like on the SQL Server at boot? Presumably you're using the recommended config here: https://docs.umbraco.com/umbraco-cms/fundamentals/setup/server-setup/azure-web-apps ?

Thanks @Jason, yes, we are using Umbraco's recommended config. Our SQL Server spikes to around 50-60% DTU (and is showing ~50% CPU usage) when the site restarts. Looking at our metrics now, I see one instance where the site restarted and the DB spiked to maxed 100% DTU and shows 100% DATA IO usage.
