Hi, I'd use the simplest logical interpretation and enter the actual physical location no matter if the actual interconnect is right there, 900 km away or transmitted from a satellite. Also, if you placed it to that location 900km away you wouldn't skew the results for your own town, but anyone measuring the latency there would see a +20ms difference from reality, so that doesn't improve anything. Many networks are large and complex, such as an ADSL for a whole country being connected to the net via a local MPLS network via a central point at one main location - should you use that one for all the probes in the country? Of course not, you enter wherever the endpoint is. If you'd like however, you can mention your specific configuration in the probe details. That's my personal view on this, others might differ.

I have been hosting one of RIPE probes and recently I have switched over my ISP.

Basically my previous ISP provider was regular ISP network with full L3 PoPs nearby but in my new setup I have got a point to point to a city 900km away and getting IP transit over there.

Now under such case, I am "technically" customer of that network. Should I still keep my location as I have current one or better update it to that new location 900km away?

The latency of course is low (as it is provisioned on fiber and hence just 20ms roundtrip) but I think it will confuse off stats if anyone considers to use this probe for any data in my region.

What you all think? Can someone recommend on correct location?

Thanks.
