All,

Sorry for the late reply.  I realize these comments come after the 12/14 deadline, but it is my hope that they can still inform any active decision processes.

I'd like to mention that some of us have calculated that the global RPKI will take a significant amount of time to crawl [1], and the algorithm agility draft (as it is currently proposed) will almost double that time, because it will necessarily almost double the number of objects in the global RPKI.  I personally worry a lot about this approach, as I feel it will likely lead to an operationally unviable standard, in which routing will be unable to adapt to changes in configuration for days, weeks, or even months, because of this design (described in [1]).

The lateness of this message is simply a consequence of the fact that our analyses have taken longer than we planned, and I do apologize for that.

Thanks,

Eric
