[ipv6-wg] Free GUA space for community projects [CfP/RFC] (was: Minutes from the IPv6 WG @ RIPE 83)

Hi Leo,
Real resiliency is possible only if everything is redundant, including the last mile.
What is the point to rent 2 fiber strands or 2 copper pairs in one cable? This cable would be cut at the same time. The non-redundant L2 device that has been used to connect this fiber may fail at the same time.
No one carrier in the world could double last-mile infrastructure. Access is 70% of their cost. Access is always non-redundant.
Moreover, access itself is typically non-redundant (just aggregation switches) couple of hops from the last mile. Well, some Carriers have redundancy on the next nodes upstream.

I am long enough on this market. I have seen many cases when different types of businesses were trying to do redundancy for the Internet.
Of course, they prefer 2 different wireline providers, but in the majority of cases, they do not have a choice between wireline providers.
Hence, the second link was 3GPP in most cases.
3GPP could be from the same Carrier as PON, but I have never heard about good coordination between wireline and wireless departments - they act as independent Carriers.

PS: In regards to anecdotes:
I am not hired/paid to collect proper information and prove anything here.
It is just my opinion based on my 25 years of experience.

The real anecdote in the industry is that there is only ULA+NPT that works for Internet site resiliency.
Everything else is broken for some reason.
Not many people know this anecdote.

Hi Eduard,

That is not my experience. In my experience, small and medium sized business owners would prefer to pay a little extra for a more resilient service from a single provider than double up on the procurement, accounting, and equipment needed when taking service from two different providers. I think my experience is most true in areas where IP services tend to be provided over infrastructure owned by a monopoly provider.

Is there any research that can take us out of the realm of anecdote?

Kind regards,

Leo
