Those actually feel spammy too; e.g. seeing "official" or "download" in a name has always triggered a suspicion, because normally there's no need to specially say your site is "official" or "download" besides to mislead.

Then again, I may be biased due to always remembering PuTTY's official page being someone's personal site hosted on a .org.uk server.

There is actually a mirror at https://www.puttyssh.org/
