We provide a non-guaranteed public access ntp service at
ntp.typotor.fi. The service is provided as-is, without
warranty of any kind. In no event shall Typotor Oy be held
responsible for any damages resulting from the use of this service.
By using our service, you agree to accept this statement.
Our ntp server operates at stratum 2, which means it derives its time from
several stratum 1 servers which are connected to external high precision
We provide our service for free for any access from anywhere in the
world, but we request that you send us an email, to the address
to notify us of your use of our server, so we can better monitor the extent
of usage on our server. You may also send us an email address to be notified
to on any changes in our server's status, if you so choose. We guarantee that
any email addresses sent to the above address will not be used to send any
other email except notifications on the changes in our NTP service's status,
which should be minimal. The source address of your notification of use
will not be used for any emailing. You must provide an address separately
with a request for status notifications to receive any email from us.
The only exception to this may be a request to use your possible local
stratum 2 NTP service as a synchronisation source to our server. We receive
enough undesired advertisement emails ourselves, that we would never
consider getting involved in such activities in any way, so your address is
safe with us.
We also suggest that you should try to use NTP servers relatively close to
your geographical location, to avoid load on the Internet and to achieve the
best time synchronisation.
Please use the DNS name
ntp.typotor.fi in your accesses to our
ntp server to minimize the impact of any changes in our server infrastructure
to your time synchronisation.
We suggest that Finnish NTP users would primarily use
the servers of Typotor and
Keski-Savon Oppimiskeskus to
synchronise their clocks, to avoid loading the foreign stratum 1 servers
too much. Even though the Finnish servers mentioned here work on stratum 2,
they are perfectly adequate to keep computer clocks in decently accurate time.
Should you wish to set up your own stratum 2 Finnish NTP service, we suggest
that you use different stratum 1 servers than we and Keski-Savon Oppimiskeskus
use. We also invite you to link your NTP service with us. This way we can
create the best possible NTP synchronisation network. The benefits of this
- Minimal load on any single foreign stratum 1 server
- Independent local synchronisation in the event one or more of the foreign
servers become inaccessible for a time
Information on the NTP Protocol can be found at
http://www.ntp.org/, and in
our ntpd server daemon's
ntp.typotor.fi, uses the NTP protocol's version 4,
operates at the standard NTP port, 123, and is a client to the following
10. April, 2008.
