Update: Friday, 22 January 2016 21:53 UTC

Root cause has been isolated to an issue within one of our backend services which was impacting which is causing periods of latency over 2 hours. Current data is no longer latent. To address this issue we have re-deployed our backend service. Current data for multiple data types is now working as expected. Some customers may experience period of data over 2 hours latency and we estimate 3 before all data is no longer latent.
