ReadyCLOUD desktop client showing Offline on multple ReadyNAS 104 - it's been disabled?!

Hi.

I have two RN104 models. One on my LAN in my office and one in a customer's office 22 miles away. The RN104 in my office is being used to store my media collection, a file server for my business and (in testing) a backup service to a small number of customers. The remote is a customer's main storage and file share which I maintain and am currently 'watching' due to problems with disk-based backups.

Both devices suddenly appeared as Offline in the desktop client for me sometime yesterday. I then got a phone call from an irate customer complaining he couldn't access his backup to retrieve a file he needed (which I then accessed locally and emailed him). This problem would have also prevented me from monitoring the problematic backup on the remote device if I didn't have VNC access and was able to access the NAS via a PC in their office.

Anyway, I left it for sometime hoping the service would return but alas no! Then I thought, just a moment ago, has the ReadyCLOUD function been somehow disabled? Sure enough, both devices have had their ReadyCLOUD function turned off. So my questions are . . .

1. Why have both devices had their ReadyCLOUD function turned off? I didn't do it and I'm the only person with admin access to both devices and they both have different, complex passwords which change regularly.
2. If this has occured due to a problem at NETGEAR, for example, a wide-ranging hack or someone 'accidentally pressing the wrong button' will you please let me know. I need to have confidence in this kit as I am installing and maintaining them for customers.
3. Is it safe to turn the ReadyCLOUD function back on? I've seen recent reports of people complaining that their data has been lost or compromised. I need to use the ReadyCLOUD client on a daily basis to manage my devices.

Thanks.
