Beware the 24 hour SLA. The service is provided over the residential infrastructure. Any noise fault, for example, will affect all the users on your optical node and that may well not get fixed in 24 hours. What the small print means is that they'll get an engineer/technician out to you within 24 hours; doesn't mean the fault gets fixed in that time. That said, area faults are rare.

The other caution is that if you take the business service, make sure that you will use Dynamic rather than Static IP addressing. The latter takes you through a very badly implemented VPN tunnel with considerable speed penalty.
