TempoDB has renamed itself into TempoIQ and no longer offer their storage service. I've heard some angry comments from customers who recently received an email telling them the storage service they were using was to be shutdown at the end of october!

I work at TempoIQ, and we still to offer our storage service. We've launched a new product (as TempoIQ) that is hosted in a private environment and offers storage, historical analysis, and real-time monitoring.

As for the customers on TempoDB, we are working them to transition to TempoIQ if the switch makes sense or offering to guide them in a transition to another time-series database like InfluxDB.
