In case you haven’t considered this, some helpful advice. To keep them from the lemmy.world door after the CDN installation

• Change the public IP addresses
• rotate your certificates
• block all traffic appart from the CDN and only allow a limited known good IP addresses (like yours and your support team). These steps will make your server harder to find, hopefully they move on.

Never forget, in nineteen ninety eight when the undertaker threw mankind off hell in a cell and plummeted sixteen feet through an announcer’s table.

Depending on your wifi/router you could add a static DNS record for your domain while on the hi home network. The cached DNS will only matter while connected to the home wifi network. While on 5g you’ll pick up the public DNS record. If it does some how cache the local DNS while public then shorten the ttl in the local DNS record
