Just to amplify this point. I've tried to claim on an SLA. Our
internet connection was down for a week due to a fire in
BT's exchange. My provider refused to do
anything (despite the premium SLA) on the basis that
fires weren't covered. I switched providers to a cheaper one
who didn't pretend to offer uptime :-)
SLA's are good for waving at management and for hiding behind
but when it comes to the crunch, they mean very little.
