To me it looks like somewhere the packets get lost or go to a network that has no idea where to send the packets (maybe due to a BGP configuration or update)

For comparison the beta system:

 ![55%20am](https://us1.discourse-cdn.com/flex016/uploads/ntppool/original/1X/6180b542affcf8337745c3341a9075fb4c498306.png)  
Notice how Zurich has a positive score

Update:  
The server score is skyrocketing upwards.  
It Looks like the issue was with equinix

I’m seeing this on one of my public servers ([http://www.pool.ntp.org/scores/103.35.80.142](http://www.pool.ntp.org/scores/103.35.80.142)). There’s nothing wrong with the link, I can reach my server just fine from a VM in the UK, and another server on a different ISP is working just fine ([http://www.pool.ntp.org/scores/150.101.178.79](http://www.pool.ntp.org/scores/150.101.178.79)).

I’m going to put this down to a BGP issue between the monitoring system and my ISP.

At this stage it’s a roller-coaster: ![offset](https://us1.discourse-cdn.com/flex016/uploads/ntppool/original/1X/46961463d0819b63c460a3e3a856aa0439705530.png)

I’ve contacted Vultr and they confirm that my instance is reachable from various locations. @ask would you mind asking phyber is they can detect any problems on their end? interestingly enough the [ipv6 address](http://www.pool.ntp.org/scores/2001:19f0:5801:414:5400:1ff:fe4b:880b) to the same instance is working without problems

My servers are in .se and I have quite similiar issue, problems on IPv4 but not IPv6. I know that the servers  
isnt overloaded so it seems to be some kind of BGP issue. My problems are not as serious as yours.  
They started about the same time.

Actually, that’s not all that surprising that you are having no issues on IPv6. There’s actually no guarantee anywhere that IPv6 and IPv4 take the same route between two arbitrary nodes on the internet. Realistically, the first hop from your server to it’s configured gateway will be the same for both (though this is by convention, not because it’s required), but beyond that, it’s impossible to say (and depending on where the two nodes are located, it may be almost guaranteed that they take different routes).

I regularly see cases with my servers where only IPv4 or only IPv6 shows a few packets lost.
