[atlas] Need host with very large ping times

I have an interesting problem: I need some host that doesn't mind being 
pinged but with several seconds of RTT (that's thousands milliseconds; 
from Moscow, but it probably doesn't matter). Amazingly, I could not 
easily find one. I even tried to ping-scan IP ranges of Antarctica, but 
those hosts that responded did so in fraction of a second. Not much luck 
with North Korea (mostly down), Taiwan (internet is much better than it 
used to be) and several other suspect countries. (Though I'm not sure my 
tests are correct, since firewall processing of such long response times 
is one of the things I'm trying to find out.)

Is it possible to somehow find one using RIPE ATLAS, preferably without 
ping-scanning whole internet? Would be especially great if it responded 
to other types of ping beside ICMP.
