photoman: Are you aware that if you've been with them for less than a year, you now face a $99 disconnection fee. Something they decided to add to their terms and conditions, but didn't bother informing anyone about. I thought companies were supposed to notify their customers of any changes to their terms and conditions.

They did not inform you because the T&C you agreed to did not change.  It is only for new customers signing up, and they are made aware of it during sign-up.  Virtually all ISPs have a minimum contract, so XNet has simply changed from a nice ISP to a normal ISP.  They have not "gone bad" or anything like that, they are just migrating to "normal".
