What region is my app's dev database located in and can I change it?

Dev databases are located in the same region as your app and cannot be migrated to another region. If you migrate your app to a different region, the app won’t be able to access the associated dev database anymore. If you need to migrate your app and dev database, we recommend either backing up the contents of the database and restoring it after the app’s migration, or using a DigitalOcean Managed Database instead. You can migrate managed databases independently of apps to different regions as needed.

Dedicated egress IPs route egress (outbound) traffic from an app. To route ingress (inbound) traffic to an app, use one of App Platform’s public ingress IPs.
Add the root domain to the list of domains in the app’s settings along with the wildcard subdomain.
App Platform apps may be slow or unable to resolve .gov domains because the domain administrators have blocked DigitalOcean’s IP addresses. To fix this, you can contact the domain administrator or use a custom DNS resolver.
