On 12-02-2020 between 22:08 UTC and 22:30 UTC, Atlassian customers using Trello may have experienced service interruptions.
This incident was caused by a bug in the version of our database running on production servers. This bug caused all of the cluster’s query routers to crash simultaneously. Fortunately, our team was already in the process of testing and rolling out a workaround for this bug, and we accelerated this deploy process to mitigate the incident.
We understand that outages negatively impact your productivity and we apologize for the inconvenience this has caused.
