"Yeahbut" - NTP is particularly aggressive about marking servers
as outliers, especially when it has a large number of servers to
choose from. It can afford to be picky. It's usually not worth
getting worked up about an outlier or two as being a bad server.
In most (but not all!) cases transient outliers are the result
of variable network latency.
