Subject: Re: NTP Issues Today
If your machines switched dates yesterday it probably means you're
NTP infrastructure is insufficiently peered and diversified.
BTW: one of the ways I discovered (almost by accident) to help make NTP more
robust is to replace a set of lines such as:
server 0.uk.pool.ntp.org iburst
server 1.uk.pool.ntp.org iburst
server 2.uk.pool.ntp.org iburst
pool uk.pool.ntp.org iburst
as NTP then selects the number of servers it thinks it needs and, IIRC, from
time to time it will replace non-responsive servers with active ones
automatically. This is in NTP 4.2.6 and later. Worth checking it out.
