# **What happened** On September 4, between approximately 10:00 AM and 11:00 AM EDT, some Vimeo users experienced partially rendered pages across the site. Affected pages displayed the top menu bar but were missing portions of the expected page content. # **What caused it** During a site update, some required files weren’t uploaded correctly. # **How we responded** We received internal notification of the issue almost as it occurred and began investigating immediately. We quickly confirmed the outage and reverted to a prior stable version of Vimeo. This restored all affected pages within one hour. We then investigated the root cause and implemented a permanent fix by roughly 1:30 PM. # **What we’re doing to prevent a recurrence** We changed the order in which Vimeo source code is uploaded and checked so that lagging updates won’t cause similar outages in the future.
