Stress Test Schedule & Engineering Benchmarks

According to Blizzard Community Manager Kaivax, this test is designed to push realm sharding and database lock contention to absolute failure limits. Starting zones (Elwynn Forest, Durotar, Dun Morogh, Mulgore, Teldrassil, and Tirisfal Glades) will have their player density limits intentionally uncapped.

Key Testing Objectives & Operational Windows

10:00 AM PDT (Realms Open)

Public realms come online worldwide. All players can create characters across 6 starting zones.

Sharding Stress Benchmarking

Engineers will restrict starting zone sharding thresholds to measure database queue handshakes and chat latency under peak load.

Beta Realm Shutdown

Closed beta realms will be taken offline permanently following this test, with all progression wiped cleanly ahead of launch.

Countdown to Oct 27

This is the final public playable session before Character Name Reservations open on Monday, October 27 at 3:00 PM PDT.
