Drysc informs us to expect rolling restarts for all US realms starting at 5:00 AM PST to apply a "minor hotfix." Downtime is expected to be minimal (around 15 minutes), and US players probably won't notice any interruption. But a hotfix? Blizzard's not said what they're fixing, which leaves us to guessing games as to the exact nature of the problem. However, poster Tuhljin seems to be on the right track when he points out that "if they won't tell you what the hotfix is for, at least part of it probably involves fixing an exploit." After all, they wouldn't keep us in the dark just for the fun of it... would they?
