thanks for the post mortem, ties.

sra commented to me that, an rp doing protocol fall-over from rrdp to
rsync, or vice versa, has to do the full download as the data structure
is so different. i.e. load spike

Perhaps it doesn’t need to be a full load: “rsync —compare-dest” (against a previously downloaded and validated set of signed objects) offers a path towards optimising the protocol fall-over.

Kind regards,

Job
