Issue Description

Hello, I hope you are all doing great.

I am building small application based on optimism blockchain and I wanted to be my application up to date as fast as possible.
I wonder if there an option to get information in which zone I should deploy my application to be really close to the optimism sequencer. I mean us-east-1, us-east-2 etc

I just want reduce latency problem.

Thank you in advance.

You can perform a forward DNS lookup from the sequencer's FQDN to obtain its IP address and then execute a ping command to compare response times. However, it's possible that something like a reverse proxy might respond instead.

By the way, why do you want to deploy close to the sequencer? Normally in dApps, end-users submit transactions to an RPC endpoint, and then those transactions are transmitted to the mempool from that node. Can you explain the background behind this?

[Rogalek]

@hash1go yes i know that I deploy some code in every region and try to ping and check which region will be the fastest but I thought easier way is just to ask developers of the optimism, because they probably know that and maybe they can share that knowledge with me?

To be precise I am asking about RPC https://mainnet-sequencer.optimism.io/

Hello. Thank you for sharing that.
It seems that the OP team has not disclosed much about how they operate the sequencer.

[Rogalek]

so I cannot get that information here?

[hash1go]

Since information not written in the documentation is not available, it is unlikely that detailed information about the location of the sequencer can be obtained.

Sorry for the delay here, we don't publicly disclose this information. You'll have to try out different regions and figure out what works best.
