(Note - as a result of this change, folks who want strong assurance of non-repudiation of ROA generation should consider delegated or hybrid RPKI setups.)To clarify, your last paragraph:
today ARIN has an HSM, for parts of the work, but requires that the user (me, mike, jared) hold ourprivate key(s) used to sign objects locally. this means that ARIN never sees the private key material.
a private key would be required to be visible/accessible to ARIN's system(s) in order to auto-updatea ROA(s) in such a new system.
Further, the future system (that will enable auto-update of ROA) will need access to the private keymaterial. This means that POSSIBLY ARIN or a bad-actor may be able to use that private key materialfor bad deeds. (note I'm not saying ARIN is a bad actor, nor that they want to do bad things)So folks that need/want to be more assured that their private key material is 'safe' will need to moveoff the ARIN Hosted deployment prior to the new system coming alive.Maybe that's all super clear to everyone else, but :) sometimes more words are more better/clear.Thanks (and Happy Holidays!)/JohnJohn CurranPresident and CEOAmerican Registry for Internet NumbersOn Jan 3, 2023, at 10:42 AM, Mike Hammett <nanog@ics-il.net> wrote:Nothing went south for me, just got an email from ARIN reminding me that they were about to expire.
The reasons you stated all make sense. We'll just have to make sure it's easy enough for the less skilled or more busy operators to comply with current best practices, lest they not do it at all to avoid the hassle.From: "Jared Mauch" <jared@puck.nether.net>

There's several reasons I can see why one would want this:
1) to ensure that proper care is maintained over the IP space, domains,
certificiates (ROA is a certificiate), etc expire and require renewal.
2) If there's a new cipher algo flaw or similar, it may become necessary
to rotate things.
3) to help avoid some of the problems that exist with unmaintained IRR
objects.
There's more I'm sure, but this is one of the reasons that I
personally have been hesitatant to roll out some tools, eg: DNSSEC
(which suffers from a variety of ciphers and for some cases lack of
ability to publish to parents - i think this was largely resolved).
With this increased security also comes to increased fragility,
which I suspect is what you are writing about, something likely broke
for you or someone else due to lack of checking the status of the ROA
expiration.
This has happened in the past with domains, including big name
ones, so having something setup (eg: roa watch, similar to x509watch on
*nix systems) would be appropriate.
I'm sure others can refer to tools or services that can do this,
but it's always a good idea to check your objects and watch when they go
away or expire.
