Hi,
I started to monitor packet loss and latency to one CN pool server.
After now 40 minutes, I see a constant loss of max. 1%.
I will keep this monitoring running and could spread some data after 24 hours.
Greetings,
Max

You have mentioned that Europe and Asia (China) have a better
connection than the USA and Asia (China). Care to back that up with
long term data? What I'd expect is the same periods of no loss
broken up by periods of heavy (>25%) loss.
Quoting Max Grobecker <[email protected]>:
maybe it's sufficient to connect the existing monitoring system via
a simple GRE tunnel to a network more close to China resp. Asia.
The connection between USA and Europe is very stable, the
connection between Europe and Asia is pretty good as well, the
problem
seems to be the "direct" connection between USA and Asia which is
lossy and unstable.
Tunneling the packets through Europe might help getting better
monitoring without big changes on the software.
Greetings,
Max

Being very well spread all over the world, couldn't RIPE Atlas
probes be used instead or in addition ?
I'm sure that can be done. But it requires writing scripts to analyse the
results and a strategy for creating the measurements. Probably having a
DNS server that iterates over ntp servers is most flexible.
