Would it be possible to run a crowdsourced map showing areas with outages.
Possibly twitter based?
I'm thinking something similar to the Uk snow map system, which uses feedback from users of twitter to report when snow is seen in the area. This to me seems a very quick way for Giff Gaff to establish problems, check the locality of the issue and resolve the issues. I have included a link below to the UK snow map for an idea of exactly what i'm trying to describe.
I'm not sure what this would involve, but seemed to me a quick and easy way to see any issues.
