I think the biggest issue would be a lot of relays are run as single instances without load balancing / replication.  Strfry supports it but I doubt it’s being done. And then the search relays are similarly scalable but not setup for it.  

 That's kinda what I wonder... Can it handle that level of stress test? 

And if it can't, then we flunk.  

 We faced something like it with the spam stress tests a few weeks ago. And we discovered the servers stay up but we are vulnerable to a sophisticated attack on the network.  

 How far away is nostr from being able to survive a sophisticated attack? 

 Ok, so apparently the influx didn't work out so well for BlueSky.
