Hey everyone, so as I’m sure everyone is aware Lemmy.World has been experiencing several outages throughout the last few days.
We have been investigating the root cause of these outages but believe that they are related to our current hosting provider (Hetzner) blocking access from ClouldFlare as (we think) they believe that our CDN is a DDoS’er, and is causing these disconnects to our backend server, problematic for sure.
We’ve opened support tickets with our current provider and are awaiting a response. We have no issue with being as transparent as possible with downtime. Anyone that is curious, can feel free to check out https://status.lemmy.world and https://dash.lemmy.world for up to the minute outage information. We are also looking into other fediverse friendly methods of posting status and outage updates
In the meantime, we are evaluating alternative hosting options and solutions to provide a high level of reliability to you, our users. Really, we want to say thanks to everyone for soldiering through all our technical growing pains.
Cheers

On your Cloudflare account, if there was a change in the CNAME/A record being proxied vs. DNS only, that could cause an issue, as Cloudflare would then strip headers off the request that your Apache/Nginx would be looking for.
If you enabled HTTP DDoS protection in your Security -> WAF tab (I think that’s where it is) that could do this too. Might be worth disabling.
Also check for any headers your HTTP load balancer might be expecting, that Cloudflare could be stripping.
Might be worth tailing the webserver logs to see what happens to requests coming in from Cloudflare.
