|The home4u.ch NTP servers are part of the NTP Pool Project. All
servers are connected to an external time source, and those operate as
Stratum 1 server. They are aware of pending leap seconds and will
announce them to connected clients. All servers are peering with each
other and also have each two additional different external servers
configured as reference. They have IPv4 and IPv6 Internet connectivity
and are located in the city of Zürich, in Switzerland.
If you see suspicious NTP (UDP port 123) connections from any of
your systems to one of the home4u.ch NTP servers, then your system is
*.pool.ntp.org for timekeeping. If you have
any issue with the home4u.ch NTP servers, please contact
with as many details as possible, so I can try to resolve it.
The home4u.ch NTP servers are available to the public, feel free
to use them for a few of your systems, but do not abuse them. If you
would like to use them in a larger installation, please contact
first with some more details and numbers on how you would like to use them.
Please use only the following hostnames in your configuration:
