From efb1e09a748f7b7685b184cdb5238e2d286d2b7b Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Fri, 20 Mar 2026 08:14:46 +0000 Subject: [PATCH 1/2] Replace small NTS servers with authoritative providers Remove ntp1/ntp2.glypnod.com, nts.teambelgium.net, a.st1.ntp.br, and time.bolha.one. Replace with PTB (German national metrology institute), Netnod (Swedish internet infrastructure), and SIDN Labs (Dutch .nl registry) NTS servers. This addresses abuse complaints about excessive NTS-KE traffic from our fleet to small community-run NTS servers. --- meta-dstack/recipes-core/chrony/files/chrony.conf | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/meta-dstack/recipes-core/chrony/files/chrony.conf b/meta-dstack/recipes-core/chrony/files/chrony.conf index d6c1b0f..6e635cd 100644 --- a/meta-dstack/recipes-core/chrony/files/chrony.conf +++ b/meta-dstack/recipes-core/chrony/files/chrony.conf @@ -11,12 +11,12 @@ confdir /etc/chrony/conf.d # Use a local timeserver in preference to the pool, if it's reachable. #server 192.168.22.22 iburst minpoll 2 prefer server time.cloudflare.com iburst nts -server nts.teambelgium.net iburst nts -server a.st1.ntp.br iburst nts -server time.bolha.one iburst nts server ptbtime1.ptb.de iburst nts -server ntp2.glypnod.com iburst nts -server ntp1.glypnod.com iburst nts +server ptbtime2.ptb.de iburst nts +server ptbtime3.ptb.de iburst nts +server nts.netnod.se iburst nts +server nts.ntp.se iburst nts +server ntppool1.time.nl iburst nts server virginia.time.system76.com iburst nts # Sync to pulse-per-second from an onboard GPS.
