>From what I have seen, I'm not sure these figures are accurate. Beyond
the qualifications that you offered, another factor is the size of the
network (i.e. if one carrier has three times the fiber miles and
customers of another carrier but has the same number of outages, the
"one is just the same as the other" argument might be a little tenuous.)
I will check for a direct source, if I can find it, for NANOG list
subscribers to access this information independent of any carrier or
ISP. Because of a holiday and business travel, I won't get back on this
immediately, but I'll try to follow this up in the next two weeks.

I think there are some problems with how the FCC outage reports count
things, but here goes....
FCC outage reports by year and inter-exchange carrier
1992 1993 1994 1995 1996
AT&T 3 15 7 18 17
MCI 13 12 19 9 15
Sprint 3 11 3 12 9
WorldCom NA NA NA 7 13
There are all sorts of normalization problems, different reporting
requirements (e.g. if you serve airports you have to report more
outages), some carriers report only when the must, other carriers
report anything even close to being reportable, and so on. Also,
if you know how fiber swapping works, sometimes its luck of the
draw who gets tapped when a shared right-of-way gets chopped.
For overall trend analysis the FCC outage reports serve a useful
purpose. But comparing one carrier to another is a different matter
and I'd rather they not get turned into another Boardwatch fiasco
people manipulating their numbers.
Note: I haven't gone to FCC reading room in Washington DC and counted
the actual reports myself, these numbers are third-hand from one of
the carriers salespeople. Caveat Emptor.
