Very much disagree.  Or at least, separate performance and outages.

Outage/Instability:

(Tie for 1st):

1) Shitty software from Major Router Vendors (and everyone else)
1) Misconfiguration
   a) Often caused by shitty/easy to fumble CLIs from Major Router Vendors
2) Attacks
3) Power failures
4) Cable cuts
5) (distant)Hardware failure

Performance has been covered; the only real broadband is Universities,
and relatively few transit networks can get to network large and small well.
