Score logs / json not showing most recent data

[fabianwenk]

As mention in the community thread https://community.ntppool.org/t/score-logs-json-not-showing-most-recent-data/2822

I am using the Nagios check from https://github.com/mj/nagios-ntp-pool
to check the scores of my servers. It does use this URL:
https://www.pool.ntp.org/scores/62.2.85.186/json?limit=1

It seems to constantly reporting a score of -0.1, but on
https://www.ntppool.org/scores/62.2.85.186 the recentmedian score is
fine with ~20, the legacy score shows quite often different values. This
is an IP address which has a long history of often being difficult to
reach from the previous monitoring system. It seems that some of my ISPs
transit carriers are doing some filtering / DDoS protection. This can be
seen with around half of the scores in "testing" being negativ.

Another server (https://www.ntppool.org/scores/62.12.173.11) is just
fine and also the json looks good with reporting a score of 20:
https://www.pool.ntp.org/scores/62.12.173.11/json?limit=1

Could it be, that the score in the json output still does use "old" (or
even stale) data? The IP 62.2.85.186 had a too low score since 13th
March 2023, so before the new monitoring system went into operation.

And the reply from NTPman:
That realy looks old data, the timestamps are 1679120256 and 1679120034 in the json, which means 18th of March.
