We have another phase of UI improvements which should reach the live site this week; we're updating the panel on the left of the exchange which deals with markets and open orders etc - adding the ability to only show particular coins, being able to sort the lists by change/volume/price/ticker; making our notifications only include delta updates for the sake of using much less bandwidth and making the chat/trollbox opt in, rather than loading on every page load. Exciting times for us.

Unsure why the site appeared down for you this morning; some kind of DNS related drama?
