On March 3, 2015, the Salesforce Technology Team observed a performance degradation issue affecting Knowledge Base Search on the EU1 instance. The problem began at 9:10 UTC and was resolved by 15:56 UTC. During this time, a subset of customers may have experienced an inability to search for recently created or modified Knowledge Base records. Thank you for your continued business and patience during this situation.

Root Cause: The problem was caused by resource contention on one node of the EU1 database tier, affecting the resources available for Knowledge Base indexing. Action was taken to reduce resource contention, allowing normal Knowledge Base indexing performance to be restored.

Actions to Prevent Future Incidents:

The Salesforce Technology Team -

- Is performing additional changes to reduce resource contention on the EU1 database tier

- Is investigating better ways to manage resource contention within our database tiers
