Root Cause
Some users were unable to log in because their accounts or IPs were flagged by an overly strict rule that blocked access based on shared IP usage.
Resolution
The restrictive rule was disabled to restore access, resolving the login issue.
Action Plan
The team refined the rule to better align with expected behavior and is monitoring its effectiveness to reduce false positives. They are also improving error handling, organizing a workshop on platform security, and evaluating ways to enhance privacy for specific attack vectors.
Resolved
We have successfully updated our internal settings, and users are now able to log in again. More detailed information about the case will be provided in the post-mortem.
Monitoring
We are continuing to monitor for any further issues.
Monitoring
We noticed some users might have faced login redirects to a block page with the message "The owner of this website has banned you temporarily". We have updated our settings internally and are monitoring the results.
