You've only lost three of the last 8 samples from that server. You will
have to wait until there are rather less recent samples available before
it gets disqualified.
Also, I have a feeling that, if it is the only one, it may stay selected
until the root dispersion grows too large, as it was the last valid
system peer and the estimated error is still acceptable (downstream
systems can make their own judgements, based on root dispersion, as to
whether or not to trust it).
