Some quick research yesterday popped up some threads elsewhere saying their QC algorithms sometimes drop sites from the map if they aren't uploading reliably, which might be the original poster's underlying issue (perhaps).
It could also be something as minor as clock skew. I'd suggest the original poster check their system clock for drift. Run ntp if you're not already doing so. The systemd timesync stuff is not as good in my experience. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
