Roblox experienced its three-day global outage in October 2021. The platform began suffering widespread connection problems on October 28, and service was restored on October 31, covering roughly 70 hours.
The outage happened during Roblox’s Halloween period, when player activity was especially high. It was initially linked by some observers to a promotional Chipotle experience, but Roblox said the incident was caused by an internal systems bug rather than a specific partnership or game.
The disruption affected much more than individual games: users struggled to log in, join experiences, customize avatars, and use other platform services. Roblox later explained that a backend traffic-routing change involving Consul contributed to the failure. The incident became one of the longest and most disruptive outages in the company’s history.
A common mix-up is November, because Roblox published updates and explanations in early November. The outage itself, however, began and ended in late October.
