Cloudflare Partial Outage - Global Tuesday 18th November 2025 11:33:00


We're seeing an increase in 500 errors from MastodonApp.UK - We are investigating.

We are confident that full service is restored. For the time being we are not reactivating the CDN for MastodonAppUK and Universeodon.com as initial feedback suggests the performance is better without the CDN. Media and the relay will continue to route via the CDN.

Monitoring detects that all services have been restored and Cloudflare report the majority of their systems are now operational. We've had to re-enable the Cloudflare proxy in front of the relay as it looks like some clients are not recognising the LetsEncrypt certificate being used however for the time being we're going to leave the MastodonAppUK site and Universeodon site directly connecting to our infrastructure to ensure all services fully recover.

For MastodonAppUK, Universeodon.com and the Universeodon relay we have disabled routing via the Cloudflare CDN for the time being. This should mean our sites will be online and operational though may be with increased latency for users further from the UK. We are continuing to monitor the situation.

We are unable to do a lot to mitigate these issues, if absolutely necessary we may be able to re-route our traffic away from the CDN and directly to our DC routers however this is likely to have a major performance impact for users further away from our UK based servers. We will continue to monitor the situation while Cloudflare work to remediate. You can follow the cloudflare incident here - https://www.cloudflarestatus.com/incidents/8gmgl950y3h7

We can see the issue is with Cloudflares global network and appears to be intermittent, our monitoring continues to confirm there are global outages intermittently across all of our sites which use Cloudflare as a CDN.

The issue appears to be far more widespread with issues now impacting the Universeodon relay and the Superior Networks website as well. We're also seeing outages across our media endpoints and other services. We believe this to be an issue with Cloudflare.
