Hi Andrew,

Taking into consideration your call for transparency, do you think the RIRs could add a section on the document where it is clearly stated what are the roadblocks to have a single root? I believe the document describes the problem and one technical feasible solution but not the full solution space. We need to understand that this is a decision from which we will most probably not turn back (we are basically deciding that there will never be a single root).

Finally, I can read in your email that you mention that this is a request from “the RIR folks”. Are you referring to RIR staff? The boards? The communities via a bottom-up process?

Best regards,
Roque

Understood, with the caveat that since it's the politics which are
pushing the wrong technical solution here, any technical discussion
will loop back to politics as soon as one asks "why?"


totally agree/understand.

I'm ignoring "upstairs", because that is also political.


yes, sorry I was trying to not point fingers at particular people/things :(

Stripped of the politics, we're having this conversation because the
RIRs are proposing to operate five roots instead of one, with each
root allowed to claim ownership over the known universe, because
actually coordinating with each other is Too Hard.  Or maybe it's more
than five, some of the RIRs have extra roots just for fun, but let's
take it as given for now that they'll collapse back down to five.


ok

The problem with multiple global RPKI roots, as KC Claffy put it
rather neatly many years ago, is that it pushes responsibility for
fixing RIR coordination mistakes (which the RIRs apparently believe
are a serious issue, as evidenced by the draft under discussion) onto
the relying parties rather than forcing the RIRs to fix those issues
on the CA side.  This is technically broken.


I think it means that since there is no single root coming 'soon', the RIR's are taking a step to move forward with rpki despite the 'no single root' existing. Ideally they would have a method to keep from being out of sync in their processing of requests/changes. Ideally that process would be outlined in the document here so we'd be able to say: "Ok, as the rpki lives on, how does X and Y and Z get done? what happens at X step 3 when Carlos decides to take a very long lunch? how does the process move along? what checks/balances are there?"

That's the part that you're referring to as KC's comment, I think?

Generating a single RPKI root is not hard.  It can be done by a cron
job.  I ran one for years, for experimental purposes, entirely from
data already available to the RIRs.  The only real issue is which
database to believe when they disagree -- which is exactly the problem
the RIRs are trying to push onto the RPs with this document.


I don't disagree that running a CA is 'simple'... I think though that if the RIRs are in a position where there won't be a single root above them 'for a while' (it's been ~10 yrs at this point) but they feel they need to move forward with something, is this direction acceptable? is it better to document that decision and it's gotchas than to not move forward at all? or to 'continue waiting for the single root' to arrive?

Chris,

fully agree, the intent is to provide unity and transparency on how the RIRs handle their respective trust anchors at this stage

Andrew



Which brings us back to bad technical decisions and political reasons.
Sorry.

yup.
