No battery backup of NBN data connection

I'm not sure if everyone out there is following the National Broadband Network (NBN) as closely as I am, so I thought I should point out one small snippet that I know a lot of people are missing. In fact, it was only recently confirmed for me when reading the NBN blog yesterday.

The UNI-D port will not have battery backup.

This means of course during a power outage you'll lose your internet connection. If you do opt for the battery backup option it will only back up voice services connected via the UNI-V port (up to 5 hours of talk time is the stated backup). Now, initially this struck me as quite a silly option, however on second thoughts it does make some sense. I can't imagine too many people will be connecting to the NBN with an ethernet cable and a laptop. Most will use some form of router, most likely with wireless. This of course would also require some form of battery backup. So really if people want to ensure their internet connection (and any voice services delivered over the UNI-D port) they'll need a UPS providing backup to the NBN CPE and their router.
