Comment Do not rely on untracked/out-of-band documentation (Score 1) 26
Canonical should pay the Internet Archive to keep a read only copy available.
Better, yet, it seems that projects that rely on paste.bin discussions should have been using a source control repository to keep them.
People need to treat discussions as the "live" part of technical documentation (which opens another can of worms, obviously.) But, if it is not source-controlled, assume it is ephemeral, or that it doesn't exist.
This also applies to stuff we cite in Stack Overflow. It's handy to cite a finding when documenting a code change, hack, or design decision based on an answer found in SO. But for very important stuff, additional documentation must exist somewhere, preferably source-controlled.
