Description of Issue: We have been made aware of an issue for some Customers production Orgs losing access to all SVMX and Salesforce Objects for all users except Administrator.
Action Being Taken: Salesforce Trust has updated with the following: Salesforce has completed the testing and validation of a fix to restore permissions for users of sandbox instances affected by this incident. We deployed and validated that fix on CS91, CS17, CS47, CS12, CS53, CS25, CS7, CS52, CS59, CS23, CS60, CS61, CS94, CS95, CS77, CS8, CS64, CS96, CS97, CS93, CS15, CS16, CS78, CS11, CS13, CS50, CS30, CS20, CS21, CS68, CS19, CS10, and CS71 and the users’ permissions on those sandboxes have been restored to their pre-incident state. If customers on those sandboxes continue to experience issues, they should log a case with Salesforce Support. This fix will be rolled out in a phased approach as analysis of readiness for each sandbox is performed. We do not have an estimated time on completion of that rollout.
The fix will not affect sandbox orgs that were refreshed after the incident began, nor sandbox orgs requested by customers to remain as-is.
