The connection is, for all intents and purposes, rather stable. The latency is respectable, but not fantastic - certainly manageable. Over this 6 hour period I continued to experience around .4 seconds of delay regarding AOEs and summoning mounts (spell casts, horn goes off - takes half a second before I'm actually on the mount). I can't remember any other specific cases where it was noticeable.

Now, given the numbers I've posted, you'd obviously expect 121ms of delay plus a few additional for processing and such, but .4 seconds is a fair bit beyond what you would expect even in the worst of circumstances. Taking actual network latency into account I believe that the .3 second discrepency that keeps being mentioned is relatively accurate.
