Salesforce data centre crashed during scheduled network maintenance carried out on 15 November 2013, which disrupted customers’ CRM and data services across the US and Europe.

According to the company, about seven out of 17 instances in North America were hit with the outage, in addition to two out of four in the Europe, Middle East and Africa region, while two in the Asia Pacific remain unaffected.

The company revealed that the initial results refer to scheduled maintenance on networking equipment that evidently didn’t work as planned.

Salesforce said in a statement that on 15 November the salesforce.com Technology Team resolved a service disruption affecting the NA2 instance.

"The problem began at 01:51 UTC and was resolved by 04:51 UTC," the company added.

"During this time, customers may have experienced an inability to access or intermittent errors to Salesforce application."
