Hi.

Since a few weeks ago, I detected many new servers on the Portuguese zone, from the provider "kashra-server.com".

Using the PT zone, on chrony config:
pool 0.pt.pool.ntp.org iburst
pool 1.pt.pool.ntp.org iburst

$ chronyc sources -v

These servers are located on the other side of the continent, lacking precision due to the network latency (see above):

The server is marked to serve on the PT zone (e.g.):
https://www.pool.ntp.org/scores/ntp66.kashra-server.com

Is this supposed to happen?

Thanks.
