From 12:54 PM PDT on September 22, 2023 to 09:13 AM PDT on September 25, 2023, custom emoji rendered as text for a small number of Enterprise Grid users.
We made a code change that inadvertently introduced unnecessary logging for routine emoji events. This unexpected logging increased traffic to the custom emoji infrastructure, impacting its performance.
We deployed a fix to remove the unnecessary logging, which reduced traffic to the custom emoji systems and restored normal emoji rendering.
A small fraction of the affected customers may have experienced lingering issues as the fix was gradually rolled out to everyone.
Note: Due to an internal tooling error, we initially reported the times in this summary in UTC, but labeled with PDT. We have corrected this mistake and apologize for any confusion caused.
