    Relevant metrics have remained normal for three full days and we consider the incident resolved.

    The root cause was a recent minor version library upgrade that included performance enhancements, but also an unexpected side effect on how we handled reconnections, particularly when a computer wakes up from sleep. Our team was able to adjust for the upgrade change, so reconnections would again be immediate, resulting in faster post saving like before.

    The post should eventually save and there is no system degradation or increased failure to save. We are investigating why our application client is not attempting to save immediately or sooner when it could and should.
