You should have at least two external servers with offsets
less than 100ms. Note than 205.151.222.251 has been
removed from consideration.
The first character on the
status line should be * or +.

Reach should be 377 indicating the last 8 requests where
successful. Check the firewall is passing port 123
if you have 000 for external
servers
