Local DNS suffix is now cable.virginm.net
4 days ago I received and setup my Virgin Hub 3. I then put the Hub 3 into modem only mode and connected this to my Linksys Velop mesh WiFi router. Everything was working fine until the early hours...

Use of Google Public DNS on your Router totally bypasses the VM Web Safe ( Child Safe & Virus Safe ) function.
The .local addresses are used on your home intranet LAN which is hosted by your 3rd party Router,
I would suggest that was the place to start investigating for any config changes. ( e.g. Wi-Fi AP Isolation )
The "cable.virginm.net" can only be seen from the public internet for the Hub public IP hostname,
e.g. via https://whatismyipaddress.com/
I can't find any setting for AP isolation.
My router does seem to be setting cable.virginm.net as a DNS search domain on my devices and some of them are responding with that suffix in their hostname when I do an nslooup on their IP address. Even the router itself does.
