thanks for your input.

Let me clarify a bit what I'm proposing. I'm not proposing a new
subscription based service operated by LACNIC (maybe LACNIC offers already RPKI alerting like
RIPE NCC's RPKI dashboard does, I'm not sure).
I'm proposing a one time
email from LACNIC to their affected members (~180) to give them a chance to solve the problem before it
significantly impacts them.
After that - and especially due to the adoption of RPKI by big service providers like Cloudflare, there
will be an immediate feedback loop when new misconfigured ROAs are introduced.
That immediate feedback (broken ROA created -> reachability impacted)
that was missing up until now, will keep the number of broken ROAs down as long as operators
care about the reachability of their prefixes (without further LACNIC notifications).

The email for affected members would not be in form of a question,
it would simply be a friendly notification stating that the reachability of their prefixes
suffers from misconfigured ROAs.

Even if existing reporting systems do include RPKI alerting, that does not
inform affected operators of their unreachable prefixes unless they actually subscribe to such
My assumption is: Every operator would like to know if his prefix
is unreachable - even if they are not aware of the problem and did not subscribe to such
alerting systems. Operators that subscribed to such alerting systems are unlikely on the
list of affected operators.
So if the options are (there are more than a and b in reality):
a) no notification is send and operators run into a hard-fail scenario while route origin validation is
increasingly deployed (i.e. Cloudflare)
b) LACNIC informs their affected members and gives them a (better) chance to solve the problem
before it significantly impacts them
then I prefer (b) over (a).
