## Timeline of updates

- **resolved** 2023-01-06 00:20 UTC: All services across all environments are now working as intended. After additional debugging, we have found that a demon for deprecated security configurations from a third party vendor in our production Google Cloud infrastructure may have been a primary contributing cause to the issue. The demon has incorrectly added ip table entries inside the node that is running the FF service causing packet drops. Upon isolating this demon and its corresponding configurations, alongside other changes, we see that all functionality is working as expected over a prolonged period of time, and we have been able to reproduce the restored services across all environments. We will monitor services for reliability while we continue working on a deeper root cause analysis and remediation plan in the coming days.
