It’s too narrowly focused. There are instances that are down for everyone, and instances that are down for just some users (like Tor users). An instance might be a constant deliberate state of blocking certain demographics (Tor/VPN users, IPs from certain regions, CGNAT, etc). Please be aware that Cloudflare sites like #lemmyWorld are exclusive walled gardens. These are not good places to collect or discuss website availability. One absurdity that we have is that websites like the original downforeveryoneorjustme(dot)com are Cloudflared, which excludes some people from doing checks (yikes, they can’t even troubleshoot a possible #digitalExclusion problem because of digital exclusion). The web is so broken… this community which tries to track and investigate the brokenness should be open to all. So I suggest:

• Renaming the community to something more generic like “Fedi Node Availability Status” and expand its scope described in the sidebar.
• Kill off your !isitdown@lemmy.world community. Or perhaps make it announcement only and redirect people to an open venue like this one. The infosec.pub instance is ideal not only because it’s within the specialized scope of the node but also the admin is quite skilled at securing the site without CF.
• Add downinspector.com to the sidebar as a suggestion for where to test sites. This is perhaps the only availability checker that is not in Cloudflare’s walled garden.
• Perhaps pin my next post, which will list some sites that always have reduced availability
