Yes, but that redundancy does not help me as a node operator. In fact, the current requirements are really strict and at least datacenter-level and actually even more strict than that, considering that
- a datacenter usually has multiple employees who look after the servers, so somebody going on vacation is not problem, where I am alone and if I go on vacation, my node has to survive without any physical intervention
- datacenters usually have scheduled maintenance where it is allowed to take the server down for some time (usually negotiated with the customer when it is least annoying to do so)
- datacenters have backups, so in the unlikely event of something really bad happening, you can restore the data.
- datacenters have different contracts with ISPs, where problems are solved fairly quickly, while a residential connection may stay down until the next working day.
Well, I do not really want to do something where I know I will not be able to meet the requirements and need to start over multiple times. For example, if I had only one internet line, if the ONU failed during the weekend, it would not be replaced until Monday, getting 40 or so hours of downtime.
The “no backups” part worries me a bit though - what if my node loses data because of a bug in the software? It’s something that I cannot really control and RAID would obviously not help there.
