However if you are selling a network service and if you care about uptime and if you are willing or able to pay for it then you get redundant connections that don't share a single point of failure. If you don't have any reason to really care about reliability, you can always do things the way LL does.

Note that the internet was designed from the start to allow connectivity to continue in the event of arbitrary intermediate node failures. That they can't get the hang of 40 year old telecommunications protocols is not the fault of their ISP; it is LL's failure in comms specification and purchase.
