The following fedi instances are perpetually exclusive because they sit inside Cloudflare’s walled garden:

• lemmy.world
• sh.itjust.works
• zerobytes.monster
• lemmy·ca
• lemm·ee
• programming.dev
• lemmy.zip

If you cannot reach these instances, there are many possible reasons:

• you use a VPN
• you use a browser Cloudflare discriminates against while also using Tor
• you are using a public library PC
• your ISP uses CGNAT to allocate your IP address (often in impoverished communities)
• you have disabled image loading (because you are visually impaired, or you are on a capped uplink, or you are an environmentalist), which then triggers a false positive for being a robot.
• you are a legitimate beneficial bot (Cloudflare treats beneficial bots the same as malicious bots)

The listed sites will rarely be down for everyone but will often be unavailable to those in the above mentioned discriminated demographics of people.
