Steam scheduled maintenance usually lasts less than one hour , often around 10 to 20 minutes for routine updates. It is typically scheduled on Tuesdays during US Pacific Time early morning or late afternoon, which corresponds to periods of lowest traffic. However, if there are unscheduled outages or malfunctions, maintenance can extend longer depending on the complexity of the fixes needed. Most routine maintenance disruptions are temporary and Steam aims to restore services quickly. Valve announces these maintenance schedules in advance, usually on official forums and social media. In general, maintenance lasts from a few minutes up to under an hour.
