I received a notice from my VPS provider of an upcoming maintenance window on the hardware hosting my mailinabox VPS instance. During the window, the hardware will be rebooted and the provider is recommending that all customer VPS’s be shut down before the window to prevent potential file system issues resulting from improper shutdown. In my case, it would mean shutting down my mailinabox for ~7 hours, which I’d rather not do since I don’t want to lose mail.
Has anyone had experience with VPS hosting maintenance windows? Can my instance be left running reasonably safely?
Thanks
