Passpack keeps all non-critical applications like the blog, help center and mail server on totally separate servers from the application. Yesterday this auxiliary server had DNS issues which resulted in difficulties posting comments, contacting the help center and a backlog of emails.
The application itself was not effected as it is sandboxed separately, however the numerous emails generated from yesterday’s secure password sending release where blocked in a queue.
The queeue is now being processed and any emails sent will arrive shortly to destination.
Thanks to everyone for writing in with error details – very helpful. If you encounter any other problems, please let us know.
