Over the past stretch we have been steadily tuning the engine behind your DNS lookups, and the results are in. Everyday lookups are quicker, and the difference is biggest exactly when it matters most, when the servers are under heavy traffic.

The headline improvement is consistency. In the past, a busy moment could occasionally leave a small number of lookups waiting up to a couple of seconds. We reworked the internal parts that caused those stalls, so even during a spike the slowest responses now stay comfortably under a second. In plain terms: fewer pauses, and a smoother experience when the network is busy.

To be sure this holds up, we built our own high speed testing tool and pushed a single server hard. On just four processor cores it comfortably served around 50,000 lookups per second with almost no dropped requests, and stayed healthy past 60,000. That is many times our normal day to day demand, so there is plenty of headroom for busy periods.

We get there by handling far more requests at the same time instead of letting them queue, spreading the work evenly across the processor, and keeping popular answers ready in a fast local cache. We also measure every idea before keeping it: one experimental speed tweak this week showed no real benefit in testing, so we simply dropped it, and we added a couple of small safety checks while we were in there. Everything rolled out live with no downtime, and your lookups stay exactly as private and secure as always.
