I think it was a very large file container. I don’t remember who was uploading a lot of stuff to one? But it’s a good test we’ll be adding. (ah, @stout77 perhaps! 
).
At the moment, I don’t think there is one set up. We’ve had the idea that we’ll need to limit them in terms of data payment / capacity. But that’s not in place yet. (Looks like something we’ll need to add though to prevent this sort of thing happening).
Ah, as to the “which commit” Q @Josh , i did reply in the other thread, but to be clear: main should work with those bins, I believe. There’s be no breaking comms changes in the meantime afaik,
I think we can call this testnet DONE. I’m leaving the nodes up for now in case any of the team want to poke at anything today. But w/ the register edit issue it seems pretty clear. So we can get tests written up for that, and look to refactor or limit the code around handling them too.
