right now it seems to not be able to get to that host at all.
It was acting strange from NL/UK too.. but more like 250 to tokyo.

Curious. Russia may be even worse. I must admit I don't know a lot about Europe
routing. What I did find earlier was that India from UK wasn't too bad, using the
looking glass server of vr.org which has lots of locations.

Hmm, I'll try it on that vr.org looking glass ffrom India.

hmm.. .
so doing the go up at the end thing. Curiously my mtr I'd left running to Japan
went a bit lower. i wonder if that is congestion due to the cable break.
if I trace to www.iij.ad.jp it's a bit better

and from NZ it's 165 msec.
then you still need good connectivity to that host in india though.. best i can do is
trace back to the gateway you were using.

And yeah it's way too high, and oesn't seem to even get to there.
There may be better routes through Pakistan, as I seem to remember that they use
both Asia routes and Europe routes.
Best I can seem to find is Japan <-> India of 125 to 132 msec, India <-> Uk of 161 msec.
And the route from UK to Japan was like 278 to 285 going via new york/los angeles.
That said the Japan traffic to India was going via Singapore, there may be a more direct
path. And I don't know if 161 is good for India <-> UK.
There's meant to be some new cable between Japan and Europe through Russia, which may help
things.
