The issues impacting users from accessing the Queries Library within Explore have been resolved. We thank you again for your patience and apologise for any inconvenience caused.
Root Cause Analysis
The initial root cause was incorrectly identified as a network/third-party issue which resulted in this second incident shortly after. Further analysis of both incidents reveals they were caused by the implementation of a new date formatting library in the Explore frontend. The new library was implemented with an incorrect date formatting configuration which led to requests sent to the backend to fail due to a format mismatch.
To fix this issue, our engineering team reverted the deploy that contained the new library. The new library has been rolled out again following the incident with the repaired configuration.
- Additional logging to reveal Graphql API errors in Explore logs [Scheduled].
- Fail gracefully on Graphql calls to prevent full page crashes [Scheduled].
