sorry, we do not support networking to sweden

Lief,

Just a clarifying question: Are you concerned about the 0.8% loss to the first hop, or the 1.1% loss to ping.sunet.se? The perceived loss along the path could certainly be control plane policing/ratelimiting/etc. Are you experiencing bad performance?

Thanks!

  • Jim

comment:4 Changed 2 years ago by leifj@…

no its the 58% packet loss between our network and the telecom argentina network

comment:5 Changed 2 years ago by leifj@…

and yes - at the time I was experiencing severe issues using ssh to several boxes on my network

comment:6 Changed 2 years ago by leifj@…

I should say that I'm seeing the same amount of packet loss right now but ssh seems to fare better so... yeah maybe they are just dropping ICMP packets over there ...

comment:7 Changed 2 years ago by jim@…

If you have a moment, please come by the NOC and check with me or one of the other routing types to diagnose with you...

Thanks!

Lief,

As per your Jabber with Lucy, we'll resolve this as a non-problem. If you continue to have issues, please reply to re-open.
