[Pool] Why is my server score suddenly so poor?

Looking for some help here as I have spent a lot of time looking at this
without any improvements. :-(
Since early Friday, 17th the pool monitoring server was reporting that my
in increasingly negative scores - anywhere between -20 and -60 range. All
over up and down. :-(
So thinking that something has gone horrible wrong on my side I check:
- fibre interface (and reboot)
- switch (also reboot, no changes in some months)
- firewall config (logs and rules)
- LeoNTP appliance (reboot and also firmware upgrade as well)
- swap of stratum 1 source
- WAN utilisation (20-30%)
I am finding nothing to explain why such low scores all of a sudden.
I compared the LeoNTP box to my other stratum 1 sources and they are within
<1ms of each other - so I think time is good and not false ticking.
I also wrote a script on my Raleigh (US) server to run ntpdate against this
every 5 minutes overnight. Only 4 timeouts in the entire night and some
time this morning.
Can anyone offer suggestions as to what to check next as this causing me a
big head ache now.
Thank you for the help,
