I wrote a deep dive on how modern reverse proxies handle thousands of concurrent requests. The article walks through what actually happens inside a proxy when multiple requests arr…

This matches what I've seen too. Resolver-level resilience is often manageable centrally. The harder part is application-level recovery; especially in larger orgs where DNS behavio…

Nice. Running Unbound locally with intelligent upstream selection and caching definitely reduces blast radius from edge resolver outages. I haven't tried Unbound but I’m curious th…

DNS keeps showing up in outage postmortems, but what's often missing is discussion about recovery, not just prevention. In this post, I break down common DNS failure patterns (TTL …

This isn't a critique of DNS load balancing. DNS works well in certain scenarios (multi-region failover, coarse traffic steering), but I've seen it misapplied in cases where faster…

For client-side LB, moving active healthcheck outside into dedicated service, wouldn't it create more reliability issues with one more service to worry about? Are there any example…

> when a single endpoint in a service begins having high latency Yes, have seen this first hand. Tracking the latency per endpoint in a sliding window helped in some way, but it cr…

Agree - sliding window error rates plus client-side circuit breakers (with half-open probes and ramp-up) work really well in practice, and the recovery-speed point is especially im…

Ok, do you mind briefly describing, what issues you saw on mobile?

The idea is attractive (especially for draining), but once you try to map arbitrary inbound client connections onto backend-initiated "reverse" pipes, you end up needing standardiz…

I wrote this after seeing cases where instances were technically “up” but clearly not serving traffic correctly. The article explores how client-side and server-side load balancing…
