As has been stated numerous times on this board, feeds are provided by volunteers and not some big, deep pocket company called LiveATC, Inc.
There is no control by the site founder over whether a volunteer provides a rock solid, 100% up-time feed or decides that playing Call of Duty is more important and therefore takes the feed down. At some point LiveATC removes feeds from the list that have gone dark, which apparently is the case here.
If you know of someone who is willing to provide a feed for that airport and treat the feed like a service rather than an afterthought, then by all means enlist that volunteer.
