Business VDSL Provider Recommendation

Does your customer understand that if they have a routed subnet then that address space will be different with the different ISP.

Since you are asked for a routed subnet then I assume you are running multiple services on-prem (who does that these days?) and need inbound traffic to a number of internal services rather than just needing a pure internet connection or just a single static IP address as getting those is easy and won't require anything special.

It's VERY unlikely that you would have BGP peering with the upstream provider over VDSL so you would need to handle failover either by having an external DNS provider not hosted on-prem with a low TTL set and the ability to flick over the DNS entry quickly to point to new IP assuming that all resolution to the customer is done via DNS not to Static IPs. Since if it is Static IP there isn't really any options.

"If it were me (TM)" I would have gone with a Mobile provider who offers failover to a mobile connection where the provider picks up the tab for usage in the event of failure. I know Spark offered it in their managed GWS service and I would assume Vodafone and 2D offer it too.

Managed GWS or Wan in a week means you have a Spark Digital supplied Cisco router that has a 4G card in it and they plumb into a Private APN on Mobile and connect over UFB back to their managed environment (rather than retail broadband).

GWS isn't cheap, so you would REALLY want to have redundancy to justify the expense.

Which circles back to why host it locally when this is the core business of the big 3 cloud providers and stop having infrastructure on-prem.

"If it were me #2" I would just go with another provider and get standard retail business consumer internet service from one of the main players rather than a special managed service with a single static IP, then work-around the fact you only have a single IP to play with and run on a skeleton environment and bring up only the essential services and cut off everything else since you are running in a disaster recovery mode anyway. That would work out much cheaper in the long run rather than try to get a routed subnet. Or look to move everything to IPv6, and then use a company like Cloud flare to map your services from IPv4 to IPv6 and then you can have everything within your single /64 or /56 routed network without needing a routed IPv4 network.
