Last week, we switched our Redis database to another software. This led to user reports of timelines not updating anymore with using some clients, like Ivory or Pachli.
After investigating the issue, we discovered that this new software returns invalid data in some specific cases, which are triggered by the API those Mastodon clients use.
We have reached out to the software developers to troubleshoot this and are hopeful it will get fixed soon. In the meantime, we are also working on a way to roll back to our previous software in case we can not get this fixed quickly.
We will post more details on this incident when possible.
