Yes. In fact it means more than that as it works in both directions. Traffic on our network because it is travelling between customers of ours in the UK and hosts they are communicating over the world, 50% is handed of at LINX, 40% in the US and 10% at Stockholm. I haven't measured the equiv figures for customers in the US recently. I did a "by mouth" survey for many of the reasonably well peered people at the LINX of the above figure at the last LINX meeting, and everyone I asked was between 30% and 50% (we've tried quite hard to get our figure high for obvious reasons). Given you already have a box less than 100m away from LINX, does this mean we might see MCI routes there soon? :-) Alex Bligh Xara Networks > -scott > -- > > > From [email protected] Wed Dec 4 16:26 EST 1996 > > X-Mailer: exmh 1.6.9 960923 ([email protected]) > > To: Jim Dixon <[email protected]> > > cc: "Alex.Bligh" <[email protected]>, [email protected] > > Subject: Re: Exchanges that matter... > > Mime-Version: 1.0 > > Date: Wed, 04 Dec 1996 21:05:59 +0000 > > From: "Alex.Bligh" <[email protected]> > > Sender: [email protected] > > Content-Type> : > text/plain> ; > charset=us-ascii> > > Content-Length: 723 > > > > > On Wed, 4 Dec 1996, Alex.Bligh wrote: > > > > > > > in content and in telecoms charging) perhaps.
