From what I was told, WFH and people starting late actually really helped, in that there were only a handful of people physically in the office when it happened. But apparently the server with the source code on it was in it too. I don’t know if they forgot about off-site backups entirely, or if they thought they had them but only discovered they were incomplete or faulty afterwards I don't know what the practice was at that time, but some years later, people weren't allowed to have the source on their laptops, they had to SSH/RDP/etc in to a hosted development system to work on it, which might explain how losing the office resulted in losing the source code even with people doing WFH
