Identified
Issue has been identified as the result of brute force authentication attempts triggering IP blocking. The security apparatus is protecting user resources as intended but it's blocking is a little overzealous and blocking all IPs attempting to authenticate (both unauthorized and valid). We are modifying network security to more granularly identify malicious IPs without affecting customers. The change is being prepared for deployment.
Issue is limited to a subset of FTP users.
