Cool! Would love to see a more detailed engineering blog!

We did something similar with Pinggy: https://pinggy.io/blog/scaling_across_multiple_regions/

Of course we don't do load balancing across agents. Routing to nearest agent is a nice feature.

Very cool, love the break down and journey. We ended up with something similar, and we definitely want to do a technical breakdown! Great minds think alike! In addition, we are also globally replicating our "core" as well.

Yes replicating the "core" is also essential in the long run!

Nice, so like cloudflare without the CDN, is there also a WAF?

We have thought about adding WAF capabilities, what kind of WAF functionality would you be interested in if we did support it?

Feel free to reach out to me over email as well: niji@ngrok.com

Nice job team!
