probably not, ime. typically a lot worse, since connectivity and peering
for .il is much poorer than for USA.
matter of milliseconds? yes, 500+, in some cases.
Try to telnet or develop over ftp with 500 ms delay is painful.
>Same hardware, same visitors from around the world
>(with a slight edge for US people).
>Any idea?
develop your own idea:
1. at a candidate .il hosting service, find an ip of an machine there.
2. at a candidate USA hosting service, find and ip of a machine there.
3. go to www.traceroute.org, and run a bunch of traceroutes from all
over to .il and to USA.
There was some @sshole in .il trying to "anonymous ftp login" into our
machines in Paris last night from ras3-p104.hfa.netvision.net.il. Here�s
ping from Paris to netvision.net.il:
# ping netvision.net.il
PING netvision.net.il (194.90.1.6): 56 data bytes
64 bytes from 194.90.1.6: icmp_seq=0 ttl=238 time=576.753 ms
64 bytes from 194.90.1.6: icmp_seq=1 ttl=238 time=573.519 ms
64 bytes from 194.90.1.6: icmp_seq=2 ttl=238 time=572.935 ms
64 bytes from 194.90.1.6: icmp_seq=3 ttl=238 time=573.473 ms
500+ ms is pretty poor.
In general, and I�ve dealt a lot with .il people and boxes, the net delays
to .il from Paris are a lot worse than the 90 ms between Paris and US East
coast.
Look at this ridiculous, but common, paris-USA-Isreal route, , noting the
huge delay within teleglobe NewYork:
