How does the load balancer work?

I am using ‘eth_blockNumber’ to do synchronizing checking, but I found that the latest block numbers provided by you are not consistent, sometimes the current check result can fall behind to the last check? I guess this is caused by your load balancer as it may redirect my requests to different back-end servers. How does your load balancer work? Which load balancer are you using? Thanks!

Hi @Kai_Li, when did you last test this and can you provide your code you’re using?

I tested it this Monday, I was using web3py such like:
INFURA = “https://mainnet.infura.io/v3/mysecretID
infura = Web3(Web3.HTTPProvider(INFURA))
current_height = infura.eth.blockNumber

We made a major change to our infrastructure on Tuesday, can you test this again and let me know if it is still occurring?
