Privex Time Servers (Chrony / NTP)

Using our time server pools

Rather than add all of our time servers by hand, we recommend that you use our pool domain instead - chrony.privex.cc - your time synchronisation software should be able to determine the best server from the pool and use it automatically.

For Chrony

Add the following line to /etc/chrony/chrony.conf

pool chrony.privex.cc iburst maxsources 8 minpoll 4 maxpoll 8

For NTP

Add the following line to /etc/ntp.conf

pool chrony.privex.cc iburst

Regional Pools

We have the following per-country pool domains too, if you prefer:

  • se.chrony.privex.io (Swedish NTP servers)
  • fi.chrony.privex.io (Finnish NTP servers)
  • de.chrony.privex.io (German NTP servers)

Per continent pools:

  • europe.chrony.privex.cc (European Time Servers)
  • america.chrony.privex.cc / north-america.chrony.privex.cc (USA / Canada Time Servers)
  • asia.chrony.privex.cc (Asian Time Servers)

Our time servers (Chrony / NTP)

We have many time servers spread across Europe, which are amalgamated via our pool chrony.privex.cc

If you'd like to know about our time servers, or you want to use specific nodes, here they are:

Hostname Time Server Software Location IPv4 IPv6

se2.chrony.privex.cc Chrony Stockholm, Sweden YES YES
de1.chrony.privex.cc Chrony Falkenstein, Germany YES YES
de2.chrony.privex.cc (de2.ntp.privex.cc) NTPD Falkenstein, Germany YES YES
fi1.chrony.privex.cc Chrony Helsinki, Finland YES YES
nl1.chrony.privex.cc Chrony Amsterdam, Netherlands YES YES

#
# This is simply a domain with A and AAAA records for all Privex-operated
# timeservers worldwide.
#
# Chrony should automatically figure out which servers have the lowest
# latency and prioritise them, filtering out or avoiding servers
# with high latency relative to your system.
#
# If you have a server in one of Privex's regions, it may be useful
# to ADDITIONALLY add one or more 'server' lines for timeservers in 
# the same region, with the 'prefer' flag, since they're generally 
# in the same datacenter, or even the same rack as servers in our regions.
#
# The prefer flag will prioritise those timeservers over much more
# congested public timeservers.
# 
# e.g. if your server is in Privex's Sweden region:
#   server se1.chrony.privex.cc iburst minpoll 4 maxpoll 8 prefer
#   server se2.chrony.privex.cc iburst minpoll 4 maxpoll 8 prefer
#
# NOTE: It's not a good idea to combine the chrony.privex.cc pool with
# a continent region pool (i.e. europe.chrony.privex.cc etc.)

# Regional Pools
#
# In most cases, it's best to use the main pool (chrony.privex.cc),
# though in some rare cases, you may want to manually force chrony
# to only use timeservers local to the continent.
#
# These should be used INSTEAD of the main pool, if you want to ensure
# only servers located on the same general continent are used.
