On February 11, 2025, Facebook Messenger experienced a significant outage starting around 2 p.m. local time in Vietnam, affecting users' ability to send and receive messages, particularly on the desktop version. Reports of issues surged to nearly 1,000 cases within an hour, according to Downdetector. Users reported slow and unstable service, with some unable to access the desktop version at all. By 3:10 p.m., some users began to regain access, but new outage reports continued to be logged. This incident followed previous outages affecting Meta's services, including a December 12, 2024 outage lasting over four hours, a March 2024 disruption lasting about an hour, a global outage in 2021 lasting six hours due to a configuration error, and a 24-hour connectivity loss in 2019.
