I haven't seen anybody on Tumblr post about this yet, so here's a heads up to Neocities, Bing, and Bing-based search engine users (including Duck Duck Go):
Microsoft has, seemingly without reason, deindexed all sites that use the neocities subdomain. This means that any website with neocities.org in the URL is not currently showing up on Bing or DDG searches, including not only the main website but also every website hosted on the domain.
I've verified that this is the case for both of my Neocities websites --- which are the top results on google for their respective names, and used to be on the first page of DDG --- and every other one I've checked with neocities in the domain. This does not appear to be affecting websites with other domain names and are hosted on Neocities. It is additionally not affecting discoverability on other search engines; it is only being blocked by Microsoft.
Not sure what's to be done about this besides hope that it gets resolved. For me personally, I've been recommending DDG as a Google alternative for years, so this is frustrating to say the least (even if its not directly DDG's fault; they like many other search engines just rely on Bing's indexing). I know many people use my UTAU website to find resources for the software, and for the time being it's no longer easily discoverable to anyone trying to distance themselves from Google. Guess it's time to finally get around to getting a custom domain, but that's not an option for everybody.
