We haven't received any further failed tweets from this problem since Twitter has been back up & running and tweets are sending successfully again through Buffer as normal.

We are aware that Twitter was down for a few hours on 10/15/2020 and some tweets failed to publish in that time. We are continuing to monitor this situation, and we have seen the error rate decrease and functionality return to normal. Twitter is currently operational again and retrying any failed tweets from Buffer Publish should send posts successfully.
