Europe's euNetworks (SIN:H23, news) is on the move this last week before Christmas in the London metro area. They announced the addition of Basildon to the company's dedicated finance network, and unveiled a new ultra-low latency route between Basildon and Frankfurt.
Basildon doesn't hit the news as often as Slough, but it does happen to be where NYSE Euronext's nextgen UK liquidity hub was built a couple years back. The suburb lies 25 miles to the east of central London, the mirror image of Slough geographically. euNetworks now boasts 4.15ms one way latency from there to Frankfurt, which it says is one of the shortest available routes today.
Several commenters have suggested lately that euNetworks might be a near term target for Zayo, which could combine it with the AboveNet European assets to substantial effect. It certainly could happen, however euNetworks itself has been working the consolidation angle in Europe (Lambdanet, TeraGate) and seems just as likely to buy more as it is to sell. They've largely finished digesting the assets, and valuations are still lower over there.
