APS, just like other things, can be employed less-than-intelligently. That
doesn't make it broke.
Believe it or not, more than a few times I've actually seen circuits switch to
protect work when a fiber cut occurs on the primary path .. and, of course, we
didn't read about those on NANOG :-)
Given, had the protect path been on the same fiber that extra nanosecond
likely wouldn't of provided much protection. Obviously, they need to be
engineered and provisioned correctly.
I do agree that grooming or lack of correct provisioning needs to be
addressed, contractually, with clearly defined significant penalties
associated with failure to meet the obligation. Once this occurs, I believe
folks will begin to give more attention to such things that seem negligible in
comparison to the commission they're about to receive.
