(Old) Vodafone Maps site:
http://www.vodafonemaps.co.nz/
So here's what I think...
1: The maps site was quicker and easier to check if an address was in the Red Zone.
2: The map was more visual and interesting and you could navigate to an area when a specific addresses wasn't found via search.
3: They are throwing away good good google juice
4: There is no link on the (old) maps site to what has replaced it which is quite unhelpful
5: Many FAQ pages on the Vodafone site actually still link to the maps site, which was annoying
6: The check your address button is small, doesn't stand out and is easy to miss
7: I just want to check and address/area at the time, I didn't want to start the "sign up online" wizard because who know how many steps or what info I'll need to enter.
A waste

Unhelpful

"Check your address" button doesn't stand out

Backwards in a few ways imo.
