twtpe3-2kg9ezv has been reporting -100 for almost a week now. Is this ([time2.google.com](http://time2.google.com)) server no longer active? ---

No, it just can’t reach your server for whatever reason. It seems to be able to reach some other NTP servers just fine, but not all. ---

Well, there will indeed be a “dotted line” at the -100 line for that monitor’s plots. But apart from that, it doesn’t really screw up the graph. The displayed score scale is always from -100 to 20, even if all the scores of all the monitors are at 20. I’ll also mention for completeness that this monitor’s score will not affect your server’s overall score. ---

@theking2 a github issue to have the graph not show outliers from the “candidate” pool would be appreciated; if I am understanding your report correctly. [Sign in to GitHub · GitHub](https://github.com/abh/ntppool/issues/new) ---

Incidently the situation has not changed. twtpe3-2kg9ezv is listed under candidates with a score of -100. I know it should not concern me but doens´t this mean there a systematic problem? I understand the server itself has a score of 20 but what is wrong with monitoring if a candiate with a score of -100 (ignore the ntp) for such a long time without being dismissed as a practical candidate? btw: [Ignore clear outliers on rendering the graph · Issue #279 · abh/ntppool · GitHub](https://github.com/abh/ntppool/issues/279) ---

Long explaination short answer: Who / what select the candidates?. The process that selects the candidates is flawed. ---

Every monitor is `candidate` unless promoted to the limited set of `testing` or `active`. To be `candidate` a monitor is not selected, the other two kind are selected when their measurement quality is good enough. ---

That clears it up than. Googles ntp server is a monitor, can potentially monitor our servers (candidate) but currently is not as there is something in the path between googles ntp monitor and our servers. It probably is this forever, for whatever reason. But currenty there is no process in place the will stop the combination of monitor server and pool server to appear even when they cannot “see” each other ---

That monitor in TW has been unreachable to my server forever but as mantioned by @avij , this doesn’t affect overall score of your / my server: ![image](https://us1.discourse-cdn.com/flex016/uploads/ntppool/original/2X/1/13e297c44d8492768bcb5b1de2e59f0aba09be76.png) ![image](https://us1.discourse-cdn.com/flex016/uploads/ntppool/original/2X/b/b9be82b03f93d4e2b48e4df3a4a042108dea5a7b.png) ---

> [@theking2](#): > > Googles ntp server is a monitor, can potentially monitor our servers (candidate) but currently is not as there is something in the path between googles ntp monitor and our servers. Can you clarify one thing, maybe for the future generations.. What makes you think this monitor is Google’s NTP server? I don’t think Google has any NTP servers or pool monitors in the NTP pool. ---

FWIW: the scores from this monitor to my servers in NL (2 x IPv4 and 3 x IPv6) are all 19.9 and 20. So it appears to be functional, at least for a part of the pool. ---
