Could you potentially export your preferences and list of subscriptions to a JSON file, which you could then supply to a new instance?

This is my first comment. I haven’t experienced any bugs or lag yet. It all seems pretty cool to me.

I can’t profess to know a lot about websites/apps. But I am aware that suddenly having large influxes of users can complicate things, in terms of having to migrate to more powerful hardware, or incorporate load balancers, change to a different type of database, and other architecture changes. It’s complicated stuff, even for corporate engineering teams with a lot of resources. IDK who runs this and what exactly the financial structure is, but it appears to be run by volunteers? I personally have patience and sympathies for these people and will reserve judgement for a while.
