Today, between 10:13 and 10:27 UTC, an unexpected issue occurred during an infrastructure upgrade to improve service speed by transitioning from HTTPS 1.1 to the H2 protocol. This change inadvertently caused an authentication error during initialization, which our status page did not detect immediately due to all microservices continuing to run. However, internal monitors identified the problem, prompting our DevOps team to revert the changes swiftly.
Despite the rapid response, this incident led to a brief period of downtime. We apologize for any inconvenience this may have caused. Our team is thoroughly investigating why the modifications that were successfully tested in our staging environment did not perform as expected in the production infrastructure.
Next Steps: We are committed to ensuring the reliability of our services and are closely examining this incident to prevent future occurrences. We will keep our users updated as we implement further improvements.
