I’m a MBL Duo user from Canada. The device logs show that it rebooted (but did not reset) at 4:04 AM on the 23rd. All of my files are still intact. I didn’t give the notification email about it rebooting any thought because, coincidentally, there was a power outage at 7AM, so it didn’t seem unusual. Strangely, despite the power outage, the logs only show the one reboot at 4AM.
Some details that may be useful to others more knowledgeable about these things:
Firmware Version: 02.43.03-022
Auto Update: Disabled
Remote Access: Enabled (Automatic)
Router UPnP: Enabled
I’ve since disconnected the device from my router (and disabled UPnP). I have a full backup of all important data on an external USB drive, but there are still some files I’d like to get off it. I’ll connect it directly to a laptop to copy those files and take a look at the crontab, which I’ve been using for years to do a nightly rsync to the external USB.
