I imagine a lot of people's websites would still be accessible indefinitely since they are hosted on GitHub Pages. A lot of others would probably expire within a month due to cloud hosting not being renewed or somebody saying "I think we can turn <person>'s PC/server/Pi off that's just sitting here in the corner. Of course, many sites would have domain names expiring within a year or two, although some people probably buy domains for longer billing cycles.
