Salesforce.com was down for under an hour on Tuesday, leaving many users in the dark.
According to brief updates on the trust.salesforce.com system status site, all Salesforce.com services across all regions were largely unavailable between 12:39 p.m. and 1:17 p.m. Pacific Time in the U.S.
In addition, trust.salesforce.com was down as well, so customers were unable to find updates about the outage.
At just after 3 p.m., the company did emergency maintenance across all of its services that it said might have an additional affect on all customers.
Salesforce.com first acknowledged the issue at 12:40 with a short note on trust.salesforce.com. It did not say what caused the outage. Salesforce.com's press group did not immediately respond to a request for additional details.
Some Salesforce.com customers using Twitter said they lost service for only short periods of about five minutes.
Salesforce.com has had fewer significant outages than it did years ago when it first launched. However, as the trend toward hosted services gains momentum, such failures draw attention to the downside of using remote services.
