From Salesforce Trust @ 5/17 12:56 pm:
The Salesforce Technology team is investigating an issue impacting Salesforce customers who use Pardot, or have used Pardot in the past. The deployment of a database script resulted in granting users broader data access than intended. To protect our customers, we have blocked access to all instances that contain impacted customers until we can complete the removal of the inadvertent permissions in the impacted customer orgs. As a result, customers who were not impacted may experience service disruption. In parallel, we are working to restore the original permissions as quickly as possible. Customers should continue to check Trust for updates.
Instance List Effected:
NA42, NA44, NA51, NA33, CS21, CS25, CS26, CS30, CS50, CS51, CS53, CS60, CS13, NA63, CS12, CS23, CS52, CS54, CS59, CS138, CS99, NA146, NA92, NA56, NA50, NA57, NA49, CS97, CS93, CS79, CS78, CS67, CS66, CS47, NA58, CS18, CS64, CS65, CS77, CS98, CS11, CS10, CS9, NA32, NA68, NA62, NA37, CS70, CS71, CS90, CS20, CS19, NA77, NA72, NA65, NA46, NA66, CS84, CS85, EU7, CS91, CS61, CS62, CS63, CS68, CS69, NA155, NA196, NA99, CS17, CS16, CS15, CS14, NA87, NA86, NA78, NA74, NA73, EU8, EU9, EU12, EU13, EU14, EU15, CS7, NA39, NA40, NA76, NA88, NA45, NA47, NA52, NA53, NA54, NA59, NA60, NA61, NA64, NA67, NA79, CS8, CS94, CS95, CS96
Its safe to assume ALL instances are effected by this in some way. Comments below point to some orgs being unaffected.
Incident Link :
As of 5/17 ~3:00 pm est. I was able to regain access to na62 & cs65. The issue is still open however so some orgs may come back online before others. My permission sets & profiles all look untouched. These orgs did not use Pardot.
The Trust Incident is still listed as on-going as of 5/20. A new known issue has been created with details on how to restore modified user profiles & permissions.
Can I restore my profiles and user permissions?
Two options exist to restore production profiles and permissions from a Sandbox Copy
To determine if your Sandbox Copy contains a valid backup of the data, check the Profiles and Permission Sets in Setup under “Administration/Users”.
If your non-admin profiles are configured such that all of the “Standard Object Permissions” (Read, Create, Edit, Delete) are unchecked, then the sandbox org was impacted and is not a valid source for recovery.
Permission Sets and User Profiles can be deployed from Sandbox to Production orgs.
Option 2: Sandbox containing production profiles and permission sets does not exist
If a Sandbox containing production profiles and permission sets does not exist and there is an organizational need for you to restore, Admins can manually modify Profile and Permission Set configurations to grant appropriate access to their users.

Incident Update as of May 24, 2019:
The following describes facts as we currently understand them. Our investigation is ongoing, and we may provide customers with updated information in the future.
At approximately 9:56 Universal Coordinated Time (UTC) on May 17, 2019, Salesforce’s Technology team became aware of a user permission issue that was impacting customers across certain NA and EU production and sandbox environments.
As the team investigated, they related the issue to the deployment of an application database script that was launched at 01:45 UTC on May 17, 2019. The script was only intended to be applied to a subset of organizations that use Pardot. That change, however, was inadvertently applied to all users across Salesforce orgs that have, or previously had a Pardot license, giving those users elevated permissions for entities to which they had access within their orgs. These permissions may have been broader than the permissions those users were intended to have. Only users who already had permissions in an org received elevated privileges as a result of the script.
To protect our customers and expeditiously disable the elevated permissions given to users, the Technology team made a decision to block access to the Salesforce service for all customers on the affected NA and EU production and sandbox environments. As a result, customers who were not affected by the database script may have also experienced a service disruption.
By 01:29 UTC on May 18, 2019, access for users with a System Administrator profile had generally been restored to customers affected by the database script issue, and full access had been restored to customers unaffected by the database script issue. In parallel, the Salesforce Technology team worked to restore user permissions to the pre-incident state. That remediation to restore permissions has now been executed on all production instances. A subset of customers may still be experiencing issues with user permissions and the Technology team continues to work to restore those.
For the subset of customers who may still be experiencing issues with user permissions, administrators can manually restore permissions for users so those users can regain access to Salesforce. Instructions for administrators whose customers continue to experience issues are available in the Known Issue article. The article will be further updated as more information becomes available. Administrators who cannot resolve issues by the information in the Known Issue article should log a case with Support.
Additional remediation on NA53 / NA57 / NA59 on May 20, 2019
At approximately 11:00 UTC on May 20, 2019, the Salesforce Technology team was made aware that a subset of orgs on NA53, NA57, and NA59 instances were not fully remediated. An investigation showed that the remediation efforts undertaken by the Salesforce Technology team on those instances had not fully restored the permissions to their prior state.
To protect our customers and expeditiously disable the elevated permissions given to users, the Technology team made a decision to block access to the Salesforce service for all customers on the NA53 and NA57 production environments. As a result, all customers on NA53 and NA57 experienced a service disruption, as they were unable to access the Salesforce services. This disruption lasted from 13:50 UTC to 14:29 UTC on May 20, 2019. Once access was restored to the service, a subset of customers may continue to experience a service degradation, which includes the inability to read, update, and/or create objects within the Salesforce service. The Salesforce Technology team was able to remove the elevated permissions on NA59 before access to that instance was blocked, so NA59 did not experience the same service disruption. However, a subset of NA59 customers may continue to experience a service degradation as the Technology team is working through remediations.
Additional remediation on NA49 / NA72 on May 21, 2019
At 07:16 UTC on May 21, 2019, the Salesforce Technology team was made aware that a subset of orgs and users on NA49 and NA72 continued to have incorrect privileges. The majority of affected users in those orgs with standard default profiles now have the current default permission levels, and Salesforce is working to restore these users to their prior permission levels.
An active investigation of the incident is taking place at the moment. Once the analysis is complete and the root cause has been validated, the information will be made available to affected customers. When remediations and preventative actions have been scheduled and implemented, an update will be made available that describes the remediations and the actions that will prevent the incident from happening in the future, including potential technology enhancements, process improvements, and training and education efforts.
