Re: [uknof] Please Advise: UK - India Routing issues
Hi all, Would like to extend thanks to all the help received on and off list. Sadly despite evidence to support our position, BSNL proved not to be co-operative. We are still pinging in excess 500 - 750ms and travelling via America. After a lot of Indians shouting in a language I don't understand, we've moved to a different Indian ISP and we're now averaging 175ms. Sometimes you have to bite the bullet and swap companies I guess. Thanks again for all the help and advice, Wayne

I have been based in the UAE for the last nine years and we have had cables cut in Egypt four or five times over that period impacting performance to varying degrees.

Re: [uknof] Please Advise: UK - India Routing issues
Co-incidentally, I've just been discussing this with a customer, and have a trace from a router in Dubai going to Lebanon ... taking in a global tour as it heads off to the East. RTT is approaching 400ms and it isn't pretty :( The past few weeks have certainly been interesting for anyone in that region, or with customers there. Paul.

Re: [uknof] Please Advise: UK - India Routing issues
In Egypt a lot of these cables share the same infrastructure, even the same cable sheath. So shared fate is inevitable.
