Kunal just posted this on the Kickstarter page: (tl;dr - it's dead and they're shutting the servers down)
Iota Labs Backers,
Over the past year, we've undergone the entire journey of making Dot a reality. The team has been grateful for the opportunity to build and ship a product with your support.
Unfortunately, to continue running an IoT service like Dot, our servers have a relatively high overhead cost that we are unable to continue paying for at this time. We regretfully announce that Dot's hardware and app are no longer supported and Iota Labs is shutting down.
We are currently looking into open sourcing all of our code to enable users to run their own servers. If you're interested in this, please send us a message.
If you have not yet received your Dots, due to anything from bad postage to unfilled surveys, please contact us by December 1st, 2017 so we can process any refunds.
