I noticed yesterday morning that my time dispersion suddenly tightened up on my server... Odd...

(Sorry for the jump at the end, that is when I restarted it earlier this morning.)
At first I thought maybe NTP switched to a different server, so I logged in and noticed a couple weird things:
remote refid st t when poll reach delay offset jitter
=====================================================================
-imap.mail.rice. 10.64.99.17 2 u 432 512 377 1.768 -0.049 1.766

+ntp.quintex.com .CDMA. 1 u 383 512 377 22.333 -0.145 0.041
utcnist.colorado.edu (aka india.colorado.edu) dropped its poll time down to 64s? But also the refid changed from ACTS to NIST?
I just restarted my NTP server this morning, and for some reason it's still keeping that one server @ 64s?
Is there something I can do to dig deeper and find out why it's doing that? I didn't make any changes to my config or to my server.
The server lines in NTP look like:
server ntp.rice.edu maxpoll 9
server clepsydra.dec.com maxpoll 9
server ntp.okstate.edu maxpoll 9
server ntp.tmc.edu maxpoll 9
server utcnist.colorado.edu maxpoll 9
server ntp.quintex.com maxpoll 9
