You can get a 40gbit connection from this company https://www.tat-14.com/tat14/index.jsp for it may be around a million dollars a month. (0C 768 is currently the fastest connection you can get and I herd it works great for instant messaging and checking email :) )
you may not get the full bandwidth when connecting to routers outside of their network but you should still get a couple of gbit/s
great for downloading torrents
If money is a little tight, you can also settle with a 2.45 Gbit/s OC48 connection http://www.mazecreatort1.com/oc48.php
While slower than oc 768, you can still do some online gaming and some torrenting.
Back in 2006, a British ISP rolled out a 2Gb/s connection in Shoreditch, East London. Keep in mind, that was four years ago and it's still the fastest!
