Hi all.
I have NTP servers in Europe that are choosing Tata (6453) to get to
0.freebsd.pool.ntp.org which lives on 197.224.66.40:
traceroute -I 0.freebsd.pool.ntp.org
traceroute to 0.freebsd.pool.ntp.org (197.224.66.40), 64 hops max, 48
byte packets

NTP is not sync'ing to that address, and sessions stay in an Init state.
Other NTP servers I have in Africa are reaching the same address via
local Anycast hosters, and sync'ing just fine.
Anyone else seeing this particular issue across Tata in Europe?
Mark.
