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.
