All systems are operational.
We have resolved all of the outstanding configuration issues and full service has been restored.
We think we have identified the issue, due to some underlying infrastructure changes that we undertook as part of replacing our old network hardware some of our web server configurations have been invalid. We have confirmed this fix on MastodonAppUK and Universeodon and are working to ensure it is present on all other servers now.
We're investigating an issue relating to our new networking configuration across our services. It looks to be impacting some users ability to interact with the sites due to misconfigurations of our load balancer and network security settings.
