All, It's a few years since I've been shopping for this, so I thought it worthwhile updating my list of suitable candidates...
I'm looking for some dark fibre around London - probably two (or more) rings, the first linking some datacentres (Interxion LON1, Telehouse, Sovereign House and HEX), and the other(s) linking a number of BT Exchanges around London. I'm currently using Zayo for parts of this already, and am talking to them, but who else should I be looking at? Many thanks in advance, Simon
