You'd also want to look at more than just the count of outage reports;
the size of the outages matters, the total size of the network, and
the MTTR. If you "had to" distill it to a single number I suppose
percentage uptime is the one to use.
I'm not sure fiber cuts are common enough to make a meaningful
statement about the reliability of one carrier vs. another.
