https://github.com/sparkfun/phant/blob/master/README.md:

> Unfortunately Phant, our data-streaming service, is no longer in service
> and has been discontinued. The system has reached capacity and, like a less-adventurous Cassini,
> has plunged conclusively into a fiery and permanent retirement. There are several 
> other maker-friendly, data-streaming services and/or IoT platforms available 
> as alternatives. The three we recommend are Blynk, ThingSpeak, and Cayenne. 
> You can read our [blog post on the topic](https://www.sparkfun.com/news/2413)
> for an overview and helpful links for each platform.
