the choice seems
o when it breaks, the noc gets the call, debugs it, and it gets fixed
o when it breaks, the software does successive guesswork back-offs until
it makes it through. the performance sucks big-time, the customer
thinks the isp is at fault, but the noc does not get called and the
real problem never gets fixed.
