What people seem to forget is the service associated with business & enterprise grade connections. I've got FTTP but my internet goes out, cool, what happens? I wait up to a week, maybe more for the ISP to get it fixed and that's if they can find an issue with it. Business and enterprise grade connections come with SLA's; guarantee's to meet a certain product being supplied. Your internet fails on an SLA'd connection? The response time for most of the customers I've seen is between 15 to 60 minutes for acknowledgement and about 4-8 hours for service to either get back to normal or have a time as to when that'll happen.
