2023 Data Services Change Log and Known Issues

2022 Change log is here.

Data Analytics Maintenance

Starting Sunday, December 18, 2022, and continuing each Sunday, Bitfocus engineers will perform maintenance on the Looker system from 6 AM - 7 AM PST (9 am - 10 am ET). To ensure the best performance possible for Looker, we are making necessary improvements to the infrastructure of the Clarity Looker configuration. The Looker application may be unavailable to customers during that period of time. Standalone, embedded, and API Looker functions may be unavailable for 1 hour. Looks and Dashboards scheduled for 6-7am Pacific Time on Sundays may not run and should be changed from this time. Please avoid scheduling any new looks or dashboards from 6 am - 7 am Pacific time on Sundays. No action from customers is required.


Known Issues

We use Looker as our analytics tool. There are some issues that are vendor specific issues and require support from Looker engineers. Our Data Services engineers work with Looker engineers for investigation, troubleshooting and fixes. 

Here is a list of the current known issues:  Known Looker Issues
