You don't say when this happened. If it was recent, I stand corrected.
It was not that many years ago that the very first post was even linked here. for nostalgia. The author was Puzzled. Unfortunately, I cannot remember who linked it, which would give us a date as to when it was still accessible.
However, I do remember you were the one who informed us about some sort of crash being the reason for a specific period of time in the early years, posts not being available in the archives. A time period that was a so-called "dead-zone" due to something like a power failure or something. That particular post you made still exists somewhere in archives, I am sure. That event was quite some time later than the earliest posts, as in, two or three years later, possibly more. That has a logical explanation. The disappearance of the earlier archive sounds very much intentional, especially since it remained there for so many years.
How long ago do you believe the earliest posts disappeared?
Internet archive sites? Wayback machine? If they've disappeared completely from the internet entirely.... Well... that would suggest something quite interesting, no? ;)
