I surveyed 3326 pool servers by configuring them by IP address in ntpd with noselect around 20:00 UTC. ntpd took about an hour (possibly due to rate limiting somewhere of the UDP spews) to stabilize. Surprisingly, despite the low-rent 6to4 connectivity, only 21 of those were showing leap=11 unsynced, all due to having never been reachable. Of the rest, 285 (8.6%) report leap=00 (no insertion pending). If your server's address is listed below, consider configuring a leapfile or temporarily changing its configuration to upstream servers advertising leap to ensure your system is advertising leap ASAP. Downstream systems need time to pick up the notice, particularly those several stratum higher.
Configuring a leapfile: support.ntp.org/bin/view/Support/ConfiguringNTP#Section_6.14. This output came from ntpq -n -c "mrv &1 &9999 leap,reach,srcadr" filtered for leap=00 and simply sorted. srcadr=109.74.206.120, leap=00, reach=377 srcadr=116.193.83.174, leap=00, reach=377
