I was just about to access a custom Visualforce page in my managed package dev org when Salesforce returned the message:
Your organization has been disabled
Salesforce.com has disabled access to the system for your company. Please contact firstname.lastname@example.org for more information about this error.
This was most concerning, as I need that Org to release the managed package for a client who wouldn't be impressed while I tried to resolve the issue with support.
Any attempt to reconnect to the org gave the same message. It appeared to resolve itself about 5 minutes later while I was writing an email to support.
Does anyone know what might have caused the message?
