This incident has been resolved. We will not provide further information in a public incident report.
Summary
On May 16, 2025, from 14:00 to 16:50 UTC, some merchants experienced errors updating products, prices and collections, with the error message: Product # update error: The transaction log for database 'tempdb' is full due to 'ACTIVE_TRANSACTION' .
This started after the transaction log for database 'tempdb' became full for one of our catalog database instances. This was solved by shrinking and restarting the impacted database. We will follow-up by creating a new alarm to warn us earlier and prevent this from happening again.
Our global sales flow was unaffected during this incident.
We apologize for any inconvenience this may have caused.
