Sure, being a unique situation it also presented unique support challenges, and I seem to recall that the link was the one that most often turned red on our network map, perhaps even teasing us as it flapped up/down for a while, and we sat with bated breath to see whether it really required our undivided attention. Also I suppose that it was considered the least important of our "dedicated" customer links, being legacy/low-cost, so most of us would've welcomed an upgrade to something more "1990s". Many providers have ways of passive-aggressively dealing with legacy customers until they upgrade or go to the competition. My DSL ISP sent me into the arms of the cable provider about 12 years ago.
