If you noticed something funky going on with Salesforce and its software-as-a-service empire today, it’s not you: it’s recovering from an hours-long outage.

As of writing, Salesforce said at 1829 UTC (1130 PT) in a status update that all of its clouds are returning to normal after suffering about a four-hour downtime.

Well, all except for Salesforce’s Tableau and Mulesoft, which remain down or affected to some extent.

The IT breakdown started at 1448 UTC, and we’re told by the enterprise software giant this hit “customers across multiple clouds including, Commerce Cloud, Mulesoft, Tableau, Core, Marketing Cloud Account Engagement, Marketing Cloud Intelligence, and Omni Channel.”

As a result, “users are unable to log into Salesforce or access any of their services,” the biz admitted.

Two hours later, the team said its ClickSoftware, Trailblazer, and Data Cloud products were also affected. At first a third-party cloud provider was thought to be to blame for intermittent networking issues causing Salesforce services to fail.

Then the tech titan said, actually, a cloud provider wasn’t at fault, and Salesforce engineers “successfully executed a rollback to mitigate the issue.” By 1752 UTC, the biz said its cloud systems were getting back on track, and customers should be able to log in and use their applications as usual, as long as those apps weren’t Tableau or Mulesoft.
