[AusNOG] Best roundtrip latency to Israel?

I knew I could depend on AusNOG to explore every option - thanks :)



A colleague of mine suggested to VPN to a point half-way along the alternate direction (eg India) and see if the connection would be routed through Europe from there.  Could reduce the latency significantly, worth a shot.  Will let you know if I succeed.



Also some others suggested to tweak the TCP settings, which I will also look into – again, thanks.





Cheers

Clay

And if you drill, it is a 20,000km round trip - ~(10,000km along the chord from SYD to TLV)

SYD to TLV is 8813 great circle miles (14183km).  This gives a lower
bound on a terrestrial path unless you start drilling.
