I am a reddit refugee just discovering lemmy and exploring for the first time. However one thing I noticed quickly was the stress instance are experiencing. With the great reddit exodus and the influx of new users onto lemmy instances that may not be prepared. Is there a way to deal with instances going offline (even if just temporarly) but still accessing a single profile, subscription list, configuration, possibly even inbox contents? Perhaps there is a third party tool that can be self hosted to keep multiple profiles on different instances in sync?
