all nodes reach out for a smart contract to get the current quote - right? and they possibly do the same to check for received payments …
with people running up to 50k nodes behind a singled IP address … is it possible we’re simply hitting rate limits of the public https://arb1.arbitrum.io/rpc <<< arbitrum RPC endpoint with our queries?! … (and the larger the files the more nodes need to create quotes/check TXs …)
and @Josh doesn’t have issues because he’s connecting from out in the woods down there in the US and the variable delays to reach the DC nodes in Europe are huge enough to spread the load a bit and for him the rate limit doesn’t hit that hard …
