I hear that many people are plagued with SD card issues. But I’m running probably ten raspberry pi’s right now and while I’ve had a couple SD card issues over the years, that has seemed to be the exception rather than the rule.
Yeah, well when running remotely it must come back by itself every single time, and I was unable to get reliable results over 6 months of testing. It might 3 months until I can travel and replace a nonbooting instance, and I will not even know what is wrong!
