I can understand these concerns. Would you rather see the wg try: (a) concentrated redesign (to what, I have no idea) (b) operational guidance to operators of how to manage this risk - get new certs out inserttimeframe before the route that relies on it, etc. (There's already been discussion

sorry. late here. as ggm said, probably better than i can, a week or two after philly. if we have a parent-child chain of length L and each runs as a batch at some time interval T, then the mean time to propagate is (T/2)*(N-1) s/N/L/ randy ___

That is only true if the thing you're propagating has to travel hop by hop to the bottom of the hierarchy. So the question still stands: what is this thing that you think propagates slowly, and why does it have to propagate hop by hop? incorrect or missing cert high in chain which needs

Geoff, I'm happy to accept that the new wording is poor, but I'm pretty sure the old wording was also bad, and I think this discussion is important. The old wording could easily be interpreted to suggest that once per day was the correct frequency for pulling from a repository. (That is, I

WG Co-Chair Hat OFF Hi Matt, entities who are actually using RPKI data for routing SHOULD be fetching fresh data from the repositories at least once every three hours. 3 hours? At a first pass that seems very frequent. From a server's perspective if there are 30,000 AS's out there
