Hi, Eliot,

Packets ARE getting to endpoints. 

If the issue is that packets of certain *sizes* aren’t getting there, then NTP should find a way around that using the current port. The fact that the existing port is being filtered is on them. Moving to another port simply invites firewall managers to add that number to their current NTP filters.

At that point we need to start thinking about what is best for the Internet, and there may well be a tradeoff here.  But it really depends on what the operational data looks like, in so much as we can get at it.
